More Information

Gow-Mac Instrument 21-250 Gas Leak Detector Overview

Features:

  • Easy to Operate
  • Solid State Design
  • Thermistor-Actuated Thermal Conductivity Cell
The Gow-Mac Instrument 21-250 Gas Leak Detector can easily and quickly pinpoint gas leaks too small to detect with soap solution. The GOW-MAC gas leak detector operates on the same principle as a thermal conductivity detector. The instrument responds to any gas mixture that has a thermal conductivity value different from that of air. With an intrinsically high signal-to-noise ratio, amplification provides maximum usable sensitivity — helium leaks of 1 x 10-5 cc/sec and refrigerant leaks of 11 x 10-4 cc/sec are easily detected.

The Gow-Mac Instrument Model 21-050 Mini Gas Leak Detector is a lightweight, hand-held instrument designed to easily and quickly pinpoint gas leaks. Like the full-sized GOW-MAC unit, it eliminates the risk of contaminating the column or system with liquids. The mini detector weighs less than 1 pound (474 grams) and measures 3 1/4 x 1 13/16 x 5 1/4" (8 x 4.5 x 13cm).

The Gow-Mac Instrument 21-250 Gas Leak Detector may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
