Product Description
Wrist Reporter Model 401 with Thumb Switch – Wireless Airflow & Pressure Measurement System
The Wrist Reporter Model 401 with Thumb Switch is the heart of a complete wireless measurement system for building airflow and environmental diagnostics. It allows technicians to view real-time measurements of air pressure, velocity, airflow, temperature, and humidity directly at the wrist, improving safety, efficiency, and accuracy during field testing.
Using wireless sensing technology with specialized probes and fittings, measurements are performed remotely and automatically displayed at the user’s wrist every few seconds. The Wrist Reporter provides a continuous stream of live data that can be viewed at the wrist, hand, clipboard, or any convenient location while adjustments are being made.

System Overview
The Wrist Reporter Model 401 with Thumb Switch serves as the central display and control unit for the Wrist Reporter wireless measurement system. Readings are transmitted wirelessly from sensing modules and displayed in real time, allowing technicians to monitor conditions while making system adjustments.
The thumb switch acts as a remote “select” key, enabling users to store readings without direct interaction with the wrist reporter keypad. This makes the system ideal for capture hood testing, room pressure testing, and airflow balancing applications.
