2500 Funnel Set
A must have for all 2500 system users, this set means you will never get mixed up as to which funnel goes where. On the Reservoir Funnel, pictured right, you know it's the right one because it has a nut attached right to the funnel, so no spills anymore. On the Chamber Funnel, pictured left, just slide it on the chamber fill port until it bottoms out, once you do this you can check the fluid level with the funnel its self by observing if the fluid touches the bottom of the funnel.
For a short time if you purchase this set you will receive a Free chamber fluid fill gauge and a flashlight.

2500 ControLog Automation Software
Thunder Scientific’s 2500 ControLog® Automation Software with automatic calibration control features makes the Model 2500 extremely easy to use.
2500 ControLog fully automates the operation of a Thunder Scientific 2500 Humidity Generator and allows various device connections through a number of different interfaces. Data from the generator and attached devices is automatically retrieved and stored for viewing in either numerical or graphical format in real time or post process.
2500 ControLog Calculates the Uncertainty of the generated 2500 parameters in Real-Time using HumiCalc with Uncertainty. The user can also drop down a Mini version of HumiCalc to help calculate desired set-points.
An Auto Profile is used as a road map to automatically control the generator. The profile defines which set-point values to go to, at what rate to go from one set-point to another, and how long to stay at a specific set-point before moving to the next one. Assurance Conditions defined in the profile allow the user to make certain a particular measured value is within a specified tolerance and/or stability before the profile is allowed to advance.
3900 ControLog Automation Software
The 3900 ControLog® fully automates the operation of a Thunder Scientific 3900 Low Humidity Generator and allows various device connections through a number of different interfaces. Data from the generator and attached devices is automatically retrieved and stored for viewing in either numerical or graphical format in real time or post process.
3900 ControLog Calculates the Uncertainty of the generated 3900 parameters in Real-Time using HumiCalc with Uncertainty. The user can also drop down a Mini version of HumiCalc to help calculate desired set-points.
Graphing is a powerful tool used to view previously recorded data or to monitor the current data in real time. The graph works hand in hand with the data tabs. While the generator is in operation, data tabs store the most recent data points from the connected devices at the desired interval. A graph can be used to create a visual picture of this stored data. ControLog supports a customizable interface that works with most ASCII based serial or GPIB devices. ControLog allows the user to define the ASCII commands that are sent and/or received through the interface to communicate with the device. The system supports both “request to receive” type of communication as well as “receive only” type of communication.
HumiCalc with Uncertainty
The new HumiCalc® with Uncertainty expands on the original HumiCalc® with the ability to calculate complex humidity uncertainties with ease.
HumiCalc® with Uncertainty can make simple work of Uncertainty budgets by giving you a calculator that performs all your humidity uncertainty calculations automatically.
One of the new features of the software now displays each known item with an uncertainty field that you can expand to enter individual uncertainty components.
Once the calculation is performed, the newly calculated values are displayed along with the expanded uncertainty values at the desired confidence level.
Humidity Calibration at Half the Cost
Albuquerque, NM: Thunder Scientific Corporation, leading manufacturer of Two-Pressure Humidity Calibration Systems, has introduced a compact version of their highly acclaimed Model 2500 Humidity Calibration Standard — the Model 1200 Mini Humidity Calibration Standard.
Priced at 50% less than standard models, the Model 1200 Mini is equal in performance, providing the highest accuracy available: ±0.5% RH over the range of 10% to 95% RH utilizing the two-pressure principle, and traceable to the International System of Units (SI) through NIST-maintained standards. Reduced dimensions (24”W x 14”D x 12”H) and weight (under 60 lbs.) make the Model 1200 Mini the perfect solution for laboratories with limited space. The price makes it attractive for all companies working with restricted budgets that still require the highest accuracy available in test and calibration performance.
Virtually all functions of the Model 1200 Mini are computer controlled via embedded Windows® XP computer and Thunder’s ControLog® software. Visuals of system status are indicated in real time on an integral Touch Screen display, eliminating the need for an external computer or readout device. The system automatically performs all control functions required for humidity generation including computing humidity uncertainty and automatic calibration profiles, as well as manually entered humidity levels. All system parameters are also stored in real time.
The test chamber in Model 1200 Mini is fluid jacketed for ultra stable temperature control and performance. The six inch square chamber with 1-5/8” diameter access port is ideal for the test and calibration of today’s smaller solid-state sensors, data loggers, chilled mirror hygrometers and environmental material test samples. The Model 1200 Mini can be easily calibrated using the operator’s pressure and temperature standards and the intuitive user interface of the menu driven software makes all programming and control simple and fast.
Thunder Scientific is now NVLAP Accredited for On-Site Calibrations
Thunder Scientific has added to its scope of accreditation, on-site calibration of all series 1200 and 2500 humidity generators. Holding true to Thunder Scientifics’ commitment to quality, all on-site calibrations are compliant to ISO/IEC 17025:2005 and ANSI/NCSL Z540-1-1994, Part 1 requirements.
Thunder's Calibration Laboratory field support staff will travel to your location with traceable standards for dew-point inter-comparison, pressure calibration and temperature calibration of your Model 1200 and 2500 generator. Our field support staff will inspect and conduct all required maintenance on your humidity generator. Calibration reports include the NVLAP logo and laboratory code, “As Found” data, “As Left” data, and a concise statement of the method used.
Thunder's accredited on-site humidity uncertainties are the lowest commercially available. Our turn-around times are excellent and prices are very competitive.
Accreditation criteria are published in NIST Handbook 150:2001, NVLAP Procedures and General Requirements. Accreditation is granted following successful completion of a process which includes submission of an application and payment of fees by the laboratory, an on-site assessment, resolution of any deficiencies identified during the on-site assessment, participation in proficiency testing, and technical evaluation. The accreditation is formalized through issuance of a Certificate of Accreditation and Scope of Accreditation and publicized by announcement in various government and private media.
NVLAP has Mutual Recognition Arrangements (MRA's) with international accrediting bodies around the world, which recognize NVLAP accredited calibration laboratories. More information about the NVLAP program and MRA's can be found at http://www.nist.gov/nvlap.
