Overview
This TPM-20 digital temperature and humidity meter comes with a clear LCD display that shows both temperature and humidity readings for quick, at-a-glance monitoring. The device has an outer dimension of 48 × 28.6 × 15.2 mm and a screen size of 35.7 × 16.8 mm, with slight measurement tolerance. It is lightweight at only 25 grams (excluding batteries), making it suitable for embedded use in tight spaces or enclosures.
The meter measures humidity in the range of 20% to 90%, with a resolution of 1% and an accuracy of ±5%. It refreshes humidity data every 10 seconds (or up to a minute, depending on conditions). Temperature can be measured from -50°C to 70°C with a reliable accuracy of ±1°C at room temperature. It operates on two AG13 (LR44) button cell batteries, drawing a rated voltage of DC 1.5V.
Installing the batteries is simple: turn the unit over, slide open the battery cover in the direction shown, and insert the two LR44 batteries into the slot. Designed for panel or embedded installations, this meter is well-suited for cabinets, equipment panels, and other monitoring setups where space and readability are important.
