ZDL-300 Formaldehyde Detector Product Description:
ZDL-300 has a data storage function, can store five times the entire measurement data, including: the date, time, test points, intervals and measurement points measured values ​​of each point, RS-232 interface to download to your computer. ES300 (Z-300) Handheld formaldehyde (HCHO) detector, using electrochemical sensors, diffusion sampler. Measuring range 0-30ppm, Resolution 0.01ppm, suitable for monitoring the concentration of formaldehyde in the air. Measure the instantaneous value of the 15-minute average STEL, 8-hour average TWA and Peak. LCD display, audible alarm in the range of 0-30ppm arbitrarily set, low battery indication.
ES300 uses a unique filter technology to eliminate a variety of common indoor air formaldehyde gas measurement interference and improve the measurement accuracy and reliability.
ES300 has a single-point test and continuous test modes. Continuous mode, the test cycle can be arbitrarily set in the range 0-480 minutes, after the end of the test cycle, the test stops automatically. Testing process can always view the entire test period average and first measured value.
