The Major Tech MT90 is a mini anemometer that reads air velocity and air temperature together on a dual-line 4-digit backlit LCD. Air velocity spans 1.10 to 25m/s at ±(3%+0.30m/s), with km/h, ft/min, mph, and knots selectable. Bluetooth BLE sends readings from the MT90 to a mobile app for Android or iOS, where recordings can be viewed, organised, and shared. The moulded casing measures 213 x 54 x 36mm and weighs 172g, sized to sit comfortably in one hand.
Not every airflow check justifies unpacking a full duct kit; sometimes the job is proving a fan actually moves air. Scribbling velocities on a scrap of plasterboard in a roof space is how readings get lost between the ladder and the ute. The MT90 sits in one hand and pairs with a phone app, so each reading lands in a recording that can be organised and shared later. A low battery indicator and auto power off keep the single 9V from dying quietly in the glovebox.
An electrician commissioning bathroom exhausts can walk room to room with the MT90, reading velocity and temperature on the same dual-line display. Min and Max recording captures the swing at a register without staring at the screen, and data hold freezes a reading taken at arm's length. Shared app recordings give the builder a tidy record of every outlet checked, straight from the phone. At 172g with a moulded casing, it rides in the tool bag all week and barely registers.
The MT90 reads air temperature from 0°C to 60°C and air velocity no lower than 1.10m/s, so very slow diffuser flows fall below its range. The moulded casing carries no ingress protection rating, so keep it out of rain and washdown areas. Recording, organising, and sharing of readings happens through the paired Android or iOS app over Bluetooth BLE.
(MT90)
Air velocity from 1.10 to 25m/s and air temperature from 0°C to 60°C, shown together on a dual-line 4-digit backlit LCD. Velocity can also display in km/h, ft/min, mph, and knots to suit HVAC, ventilation, and site conventions.
The meter pairs over Bluetooth BLE 4.0 with a mobile app for Android or iOS. Readings transmit to the app as recordings that can be viewed, organised, and shared, which keeps a record of each check without writing anything down on site.
Air velocity is rated ±(3%+0.30m/s) across 1.10 to 25m/s with 0.01m/s resolution, and air temperature is rated ±2.0°C with 0.1°C resolution. Equivalent accuracy figures apply in km/h, ft/min, mph, and knots, and the display flags any overrange reading.
The moulded casing measures 213 x 54 x 36mm and weighs 172g, designed to sit comfortably in one hand. It runs on a single 9V battery, with a low battery indicator and automatic power off to stretch battery life between site visits.
Yes. Min and Max recording captures the highest and lowest values across a measurement, and data hold freezes the current reading on screen. Recordings sent to the mobile app can then be organised and shared as a record of the check.
Quick airflow spot checks rather than full duct traverses. It verifies exhaust fans, compares supply registers, reads wind speed for outdoor work decisions, and pairs velocity with temperature in plant rooms. Air moving slower than 1.10m/s falls below its measurement range.
