Automatic Calibration at the Touch of a Button
One-touch, completely automatic calibration helps prevent improper adjustments. Just attach the tubing to the sensor inlet and apply gas. Detectors display peak, STEL and TWA. Alarms include a bright flashing LED and a 95dB audible. Alarm set points can be adjusted. Units display battery level remaining. Normal operational temperature of -20° to 50°C in 15 - 90% continuous humidity (noncondensing). Patented Button™ sensors are easily replaceable. The stainless steel, solid electrolyte construction sensors contain no liquid so they won't leak. Units are 4.5"H x 2.5"W x 0.75"D and weigh less than 4.4 oz.
