Weather Sensors

Class A Accuracy sensor designed as per IEC61724-1:2021

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.

The Altair ATRH sensor, Rigel 2 module sensor, and Xtreme data logger form one bankable monitoring chain — from field to cloud.

1
Altair / Rigel
Sensor. Measure air temperature, humidity and PV module temperature to IEC 61724-1:2021 Class A.
2
Xtreme XG
Logger. Reads every sensor on site, stores the data and sends it on over Ethernet, Wi-Fi or LTE.
3
DaLI
Firmware. The web console built into every Xtreme station, for setup and checks on site.
4
Live3
Cloud. See every station, get told when something is wrong, and fix it without a site visit.
