In environments such as cold rooms, pharmaceutical storage, labs, food processing units, and healthcare logistics, viewing the right temperature is only half the responsibility. The other half is humidity. Even when temperature is stable, incorrect humidity can cause product degradation, microbial growth, texture changes, crystallization, label peeling, and reduced shelf-life. This is especially critical in pharmaceutical storage, vaccine rooms, test chambers, and frozen food supply chains, where both parameters define product safety. Yet many facilities still rely on separate or outdated indicators, leading to inconsistent readings, scattered monitoring, and poor operator clarity. The cold chain needs a clear, reliable, easy-to-read, robust indicator that shows both temperature and humidity together, with uncompromising accuracy. This is where the new SZ-9940 steps in.
A Clear View of Your Environment
The SZ-9940 is a Temperature + Humidity Indicator designed to provide unmistakably clear visibility of critical environmental conditions. Featuring a large 2-inch single-line bright white display for temperature, paired with a distinct green display for humidity, operators can instantly understand room conditions from across the facility, reducing guesswork and improving operational discipline. Its bold and differentiated display colors ensure that temperature and humidity are never confused, and never overlooked. The indicator accepts input from NTC sensors and humidity transmitters (HS-220 / HS-100 / 4–20mA), ensuring compatibility across a wide range of cold storage and pharma-grade monitoring systems. Whether it is integrated into a new room or added to an ongoing facility, the SZ-9940 adapts seamlessly. With built-in RS-485 (Modbus) connectivity, it can also transmit live readings to a central system, so temperature and humidity data can be viewed remotely on a laptop or mobile phone in real time.
Built for Critical Cold Environments
Cold rooms, especially negative-temperature pharmaceutical and food environments, require continuous monitoring, not occasional checks. The SZ-9940 ensures that the true health of the room is always visible, allowing operators to take corrective action before conditions drift out of safe limits.
Where the SZ-9940 Makes the Biggest Difference
Industry / Environment Why It Matters
Cold Rooms & Freezers Maintains product texture, freshness & stability
Pharma & Vaccine Storage Ensures regulatory compliance & potency retention
Food & Dairy Processing Protects flavor, moisture content & microbial safety
Laboratories & R&D Facilities Maintains controlled experiment conditions
Wherever products are sensitive – SZ-9940 makes the environment predictable.
In industries where margins are tight, waste is expensive, and standards are strict, clarity is a competitive advantage. And the SZ-9940 is built to deliver exactly that.
