Description
Overview
GAOTek sampling tester ammonia with zero-point automatic tracking; long-term use will not be affected by the zero drift. Multi-level calibration for target points, can ensure the linearity and accuracy of the measurements. Chinese and English interfaces can be selected. Broad operating temperatures -40 °F to 158 °F (-40 °C to 70 °C) and temperature compensation is supported. Record the calibration logs, repair logs, failure countermeasure solutions, sensor service life due reminder, and function of reminder for the time of the next concentration calibration. Meet the requirements on the design of the intrinsically safe circuits, such as anti-static, and anti-electromagnetic interference. The protection level is up to IP65, and it is possible to prevent the splash of water, dust, and shock.
