Line Seiki TH-4000 Humidity-Temperature Meter (Measuring Instruments)
Product Made in Japan
Manufacturer: Line Seiki
Model: TH-4000
Description of TH-4000
The TH-4000 stands as a portable Humidity-Temperature meter that comes with a detachable RH/Temp sensor probe and features a Dew Point Display Function.
Its core function is to monitor and regulate humidity levels, primarily intended for measuring Relative Humidity in enclosed spaces like museums, libraries, server rooms, calibration laboratories, warehouses, and similar environments.
With a measuring range of 10 to 95% RH and 0°C to 80°C, the TH-4000 offers versatile functionality.
Its large LCD display provides a clear readout of measured RH, and it comes with additional features like Data Hold and Data recording of Max/Min values.
You can easily transfer data to a PC using the integrated RS232C serial interface.
The TH-4000 is compliant with CE and RoHS regulations, ensuring quality and environmental standards are met.
