Hand-held formaldehyde detector

ES300 (Z-300) handheld formaldehyde detector / formaldehyde detector, using electrochemical sensors, diffusion sampling. Measuring range 0-30ppm, resolution 0.01ppm, suitable for monitoring the concentration of formaldehyde in the air. Measured instantaneous values, 15-minute average STEL, 8-hour average TWA and peak. LCD display, sound alarm can be arbitrarily set in the range of 0-30ppm, low battery indication.

ES300 uses a unique filter technology that eliminates the interference of many common gases in the indoor air to formaldehyde measurements and improves the accuracy and reliability of the measurement.

The ES300 has two operating modes: single-point test and continuous test. In continuous mode, the test period can be arbitrarily set in the range of 0-480 minutes. After the test period ends, the test is automatically stopped. The average value and the first measurement value can be viewed at any time during the test.

The formaldehyde detector/formaldehyde detector has a data storage function and can store all data of 5 measurements, including: date, time, number of test points, measurement point interval, and measurement value at each point. The RS-232 interface is downloaded to the computer.
