The toxic gas detection probe Overview:
TEC- series toxic gas sensor using imported electrochemical sensors and microprocessor control technology,
Module design uses a high-precision, low temperature drift precision amplifiers, power supply circuit with a stable ,low-noise design,signal processing have adopted low temperature drift and high precision device
Member, so that the module measurement high concentration stable, meantime in lower concentration detection high accuracy. at low concentrations measured by small interfering signals, provides high accuracy and stable of the measured data.
Features
adopted advanced imported electrochemical sensors, long life;
use high-precision op amps and power IC, stable, sensitive and reliable;
can accurately detect low or high concentrations of toxic gases;
product design, anti-interference ability, over-range protection, reverse polarity protection and lightning protection;
product design, low power consumption, network-based RS-485 output and digital TTL output
