Handheld Data Logger TC-37K

T-ZACCS3 Handheld Data Logger TC-37K

Faster and easier to use – a handheld data logger compatible with a wider range of sensors!

Compact, handheld design fits comfortably in one hand. 
Building on the proven performance of the previous model TC-32K, this upgraded version offers even greater ease of use. 
The new model expands compatibility with the addition of a sensor mode (1-gauge, 2-wire type), enabling a wider range of applications. 
It also supports high-speed recording with monitoring intervals of 100 msec and logging intervals selectable at 0.5, 0.2, or 0.1 seconds, allowing for more detailed data acquisition. 
In terms of operability, shortcut keys and a simplified menu structure ensure smoother, more intuitive operation. 
Despite its smaller size, the mounting screw pitch remains unchanged, making it easy to replace existing units without modification. 
This enhanced model is designed to satisfy both new users and current TC-32K owners alike.
