Temperature Transmitters
BATTERY OPERATED TEMPERATURE GAUGE
TG 20
TG-20 Digital Temperature Gauge is a reliable and cost-effective instrument designed for fast, easy, and trouble-free temperature monitoring in industrial and laboratory applications. It supports RTD (Pt-100 / Pt-200) and thermocouple (J & K) inputs, providing high accuracy and stable performance. A clear LCD display with auto display shut-off helps conserve battery power and ensures long-lasting operation. The gauge can be supplied with local or remote sensors, offering flexible installation options. Features such as unit conversion (°C / °F / °K), display lock, and fast response time (<500 ms) enhance usability. Housed in a weatherproof IP65 / IP67 enclosure, the TG-20 is ideal for harsh industrial environments.
Configure the transmitter and electronics based on application, environment, and compliance requirements.
