Introducing Dwyer Instruments HVAC Performance Monitoring Wireless Smart Sensors
Dwyer Instruments are a global leader in the manufacture of innovative scientific equipment. The team at Instrument Choice regard their meters for testing of HVAC equipment performance very highly. This article spotlights Dywer’s exceptional range of wireless HVAC sensors.
Handheld Unit or Gateway – Which Solution is Best for You?
Instrument Choice Scientists have highlighted some examples of portable and wireless options designed for HVAC testing and balancing.Within the HVAC range, there are two options for wireless connectivity, either through either a Dwyer handheld unit kit or via a gateway using a personal mobile device.
- Dwyer handheld Unit Kit: The IC-UHH2 kit comes with a gateway (IC-UHH-BTG) and android based unit to view measurements from your wireless sensors.
- Dwyer Gateway with Personal (BYO) Mobile: We recommend the IC-UHH-BTG and HVAC Mobile Meter App you would like to use your own mobile device to view measurements.
1. Base UHH2 Model
Product Code: IC-UHH2
The IC-UHH2 base unit is a kit containing an android-based handheld meter, the UHH-BTG wireless mobile gateway, two USB charging cables, charging block, mini-screwdriver, user manual, and headphones.
The android unit and wireless gateway in this kit are compatible with several wireless Bluetooth Dwyer sensors. The kit included with the IC-UHH2 provides all the functionality and versatility you will need for building commissioning, and the balancing and testing of HVAC equipment performance.

Dwyer Instruments Compatible Wireless Sensors
Irrespective of whether you choose a handheld or gateway solution, all the Dwyer Instruments wireless sensors reviewed below are compatible with both IC-UHH-BTG / HVAC Mobile Meter App and IC-UHH2 packages.
Wireless Probe, Velocity and Temperature
Product Code: IC-AP2
The IC-AP2 accurately measures air velocity, airflow, and temperature, and sends the measurements wirelessly to the IC-UHH2 base station. A 203mm probe, a robust plastic handle with a wrist strap, an LED connectivity indicator, and a protective sleeve for the sensor, makes the IC-AP2 ideal for a wide range of airflow measurement practices.
Dwyer Instruments IC-AP2 Specifications
- Temperature Limits: Process limit from -29 to 100°C; Ambient limits from -15 to 51°C.
- Range: Air Velocity: 0 to 30 m/s; Volumetric Air: 999,999 in selected flow units; Temperature: -29 to 100°C.
- Accuracy: Air Velocity: ±3% FS within temperature range 4 to 32°C; Temperature: ±0.28°C.
- Response Time: 1 second.
Wireless Probe, RH, Temp, Dew & Wet Bulb
Product Code: IC-RP2
The IC-RP2 measures humidity, temperature, dew point, and wet bulb temperature with precision and convenience. The probe includes a membrane filter that protects the sensor mechanism in HVAC ducts with higher airflow. When required, you can plug-in factory calibrated replacement humidity sensors, without the need for additional calibration.
Dwyer Instruments IC-RP2 Specifications
- Temperature Limits: Process limit from -40 to 100°C; Ambient limits from -15 to 51°C.
- Range: RH: 0 to 100% (non-condensing); Temperature: -29 to 60°C.
- Accuracy:RH: ±2% @ 25°C (10 to 90% RH); ±4% (0 to 10, 90 to 100% RH); Temperature: ±0.3 at 25°C.
- Response Time:1.5 seconds.
Wireless Probe, Velocity and Temperature
Product Code: IC-VP2
The IC-VP2 features a 100mm Vane Thermo-Anemometer that accurately measures air velocity, airflow, humidity, and temperature. Due to the large diameter of the vane, it can measure velocities down to 0.25m/s.
Dwyer Instruments IC-VP2 Specifications
- Temperature Limits:Process limit from -29 to 100°C; Ambient limits from -15 to 51°C.
- Range:Air Velocity: 0 to 30 m/s; Volumetric Air: 999,999 in selected flow units; Temperature: -29 to 100°C.
- Accuracy:Air Velocity: ±3% FS within the temperature range of 4 to 32°C; Temperature: ±0.28°C.
- Response Time:1 second.
Wireless Differential Pressure Module +/- 2" W.c.
Product Code: IC-WDPM-002
The IC-WDPM-002 is suitable for viewing and assessing air pressure variations across filters, the static pressure in ducts, and velocity pressures from pitot tubes or airflow stations. When using it with a pitot tube or airflow measuring station, you can set measurements to read in air velocity or volumetric airflow.
Dwyer Instruments IC-WDPM-002 Features

Don’t you hate it when the forecast says there’s no chance of rain on the weekend, then the weekend comes and it rains on your parade (literally)? Yep, so do we here at Instrument Choice.
This happens if your local station is located a fair distance from you, so the forecast you receive may not be accurate for you.
With a home weather station, you can have hyperlocal current weather and forecasts at your fingertips. Even more impressive is the increased functionality of weather stations. It is now easier than ever to receive real-time information and weather forecasts right to your mobile phone.
How? The answer is… the Internet.
The annual International Day of Women and Girls in Science recognises the critical role women and girls play in science-related fields while promoting the full and equal access of females to participate. As an equal opportunity employer, Instrument Choice celebrates the contribution women make. This article examines why commemorating this day matters and spotlights the extraordinary contributions Australian women have made within the discipline of science, technology, engineering, and mathematics (STEM).
