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: ±1% RH over the range of 10% to 95%RH utilizing two-pressure, NIST traceable technology. 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 Achieves NVLAP Accreditation

Thunder Scientific Corporation is pleased to announce that on June 17, 2003 our Calibration Laboratory received Accreditation from the National Voluntary Laboratory Accreditation Program (NVLAP), administered by the National Institute of Standards and Technology (NIST). NVLAP has assigned Laboratory Code 200582-0 to Thunder Scientific, indicating that our accredited calibration services are in compliance with all requirements of ISO/IEC 17025:1999, the relevant requirements of ISO 9002:1994, and ANSI/NCSL Z540-1-1994, Part 1.

Thunder's Calibration Laboratory now offers NVLAP accredited calibrations for both new and existing humidity generators. Our calibration laboratory can provide a NVLAP accredited calibration for virtually any humidity instrument.

Thunder's accredited humidity uncertainties are the lowest commercially available. Calibration reports include as-received and as-left data as well as a concise statement of the method used. 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.

Quick Calibration Turnaround Means Fast ROI

Model 2500 Two-Pressure Humidity Generator

Albuquerque, NM: Thunder Scientific Corporation brings complete humidity calibration standards to even small in-house laboratory operations with an easy use, cost effective benchtop system; the Model 2500 Two-Pressure Humidity Generator. This system is compact and completely mobile, providing NIST traceable calibration of humidity sensors both on-site and in the field. The system is ready to use within 1 hour of delivery and gives extremely fast return on investment (ROI) through its quick turnaround on virtually any humidity calibration workload.

Thunder Scientific’s ControLog™ Automation Software with automatic calibration control features makes the Model 2500 extremely easy to use, cutting set up and programming time dramatically for hands-off operation.

The two-pressure technique was recently validated by NCSL as the intrinsic/derived standard for humidity calibration (RISP-5). The Model 2500 is an excellent representative of this; providing high accuracy reference for humidity calibration. The system is capable of continuously supplying accurately known humidity values for instrument calibration, evaluation and verification as well as for environmental testing.
