Class A sensor designed to IEC 61724-1:2021 — RS485 Modbus RTU output, IP65-rated stainless steel body, -40°C to 125°C measurement range.
Product Features
Six pillars that define ALT-TH110's precision and reliability
IEC 61724-1:2021 Class A
Conforms to the most stringent Class A accuracy standard for environmental sensors — guaranteeing repeatable, reliable measurements in every deployment.
High-Precision Measurements
Temperature uncertainty of just ±0.2°C (max) and humidity uncertainty of 1% RH with 0.01 resolution on both parameters.
RS485 Modbus RTU Output
Industry-standard digital output for seamless integration with SCADA, BMS, HVAC, weather stations, and industrial automation systems.
IP65 Rugged SS Construction
SS304/SS316 housing with a porous sintered stainless steel filter withstands harsh environments and guarantees long operational life.
Indoor & Outdoor Ready
Deploy directly indoors without accessories or use the optional UV radiation shield (ordered separately) for full outdoor installations.
Multi-Parameter in One Probe
A single integrated probe simultaneously measures both air temperature and relative humidity — reducing wiring, cost, and installation complexity.
Built to Work Together
The Altair ATRH sensor, Rigel 2 module sensor, and XTREME data logger form one bankable monitoring chain — from field to cloud.
