Electrotherm Thermohygrometer Indoor Temperature & Humidity Sensor LKM 446, 0.5 °C Accuracy, -20 to 80 °C Range

Electrotherm LKM 446 thermohygrometer sensor is a low-cost, fully calibrated indoor temperature and humidity measurement device with an integrated semiconductor sensor. It accurately measures temperature over a range switchable between 0 to 50 °C and -20 to 80 °C and relative humidity between 0 to 100%, with guaranteed accuracy within 3% humidity and ±0.5 °C temperature measurement error at 25 °C.

The compact sensor, sized 70x70x25 mm, is designed for use inside buildings, industrial plants, and switch cabinets. It offers direct connection capability to evaluation units such as PC cards or PLCs via two voltage outputs, streamlining integration into existing monitoring systems.

Its screw clamp terminals accept conductors from 0.13 to 1.5 mm² and the sensor body is constructed from durable white PVC material. It holds an IP20 protection rating, suitable for enclosed spaces requiring environmental measurements without exposure to harsh external conditions.

Users are provided with two controllers for on-site minor correction adjustments, ensuring optimal accuracy according to site requirements. The device supports a lateral cable outlet option enhancing mounting flexibility.

Compliant with European EN standards for EMC emission and noise immunity (EN 61326-1:2006, EN61326-2-3:2006), this sensor ensures reliable performance in industrial and commercial settings.

The sensor delivers precise measurement for temperature and humidity in HVAC, manufacturing, water treatment, and building environment monitoring applications. It supports environmental test and measurement requirements in laboratories and industrial plants.

Compact and lightweight design (approx. 50 g) facilitates easy installation and maintenance. Robust materials and construction provide stable long-term operation in controlled indoor environments.

Environment and industry professionals seeking high-accuracy indoor environmental monitoring can employ the Electrotherm LKM 446 thermohygrometer sensor for reliable data acquisition. Explore more Hygrometers and Test & Measuring Instruments at EnvMart for comprehensive solutions.
