When you need to check torque on a bolt, a wrench, or a sensor, the reading can be fuzzy or lost completely. Inaccurate torque leads to loose parts, broken equipment, and costly re-work. You also need a way to store the data for reports or later analysis. The Tohnichi CD5 Compact Digital Torque Indicator with RS232C Data Logging Display solves these issues. It gives you a clear, precise readout and saves up to 1,000 readings, ready to send to a PC or printer.
Tohnichi CD5 Compact Digital Torque Indicator with RS232C Data Logging Display with Tohnichi
Get instant, accurate torque numbers on a bright LCD and log every measurement with a single device. The CD5 is a compact display that works with strain-gauge sensors, torque wrenches and rotary torque sensors. If you struggle with guesswork or manual charts, this tool gives you a digital readout and automatic data transfer, so you can trust each tightening step.
