Product Features

Patented Sensor Technology

The instrument uses Labthink’s proprietary infrared sensor for water vapor analysis, which has excellent precision, repeatability and service life. Higher sensitivity and stability make it unnecessary to calibrate with distinct reference films for different test ranges and the interval between calibrations is extended. The test range of the sensor can be set automatically according to the transmission rate of the specimens without manual adjustment.

New Generation Integrated Testing Block

The patented three-cell integrated test block structure using advanced thermodynamics and hydrodynamics analysis greatly improves the temperature, humidity and flow measurement accuracy across the three test cells and supports sequential testing of three samples.

Automatic Control of Temperature, Humidity and Flow Rate

The internal temperature and humidity of the instrument are automatically adjusted with temperature and humidity sensors, maintaining the stability of the test specimen environment. Automatic flow rate control ensures constant flow during the testing process and minimizes any errors caused by an unstable flow rate.

Easy-to-use and High-efficiency System

The automatic test mode, combined with the instrument features, eliminates the need for manual adjustments to quickly obtain accurate results, saving training costs and releasing staff from manual monitoring so that they are available for other tasks.

The professional test mode provides flexible and rich instrument control functions to meet individual scientific research needs.

Unique, optional DataShieldTM system, meets the requirements for centralized management of user data. It supports a variety of formats of exported data. Reliable security algorithms are used to prevent data leakage. It supports universal wired and wireless LAN, optional private wireless network and third-party software.

User-oriented Service Concept
