Air Temperature and Relative Humidity Sensor

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.

  1. 1

    Altair / Rigel

    Sensor. Measure air temperature, humidity and PV module temperature to IEC 61724-1:2021 Class A.

  2. 2

    Xtreme XG

    Logger. Reads every sensor on site, stores the data and sends it on over Ethernet, Wi-Fi or LTE.

  3. 3

    DaLI

    Firmware. The web console built into every Xtreme station, for setup and checks on site.

  4. 4

    Live3

    Cloud. See every station, get told when something is wrong, and fix it without a site visit.
