data loggers for temperature

Kingmach Measurement & Monitoring Technology Co., Ltd. builds temperature data loggers that engineers actually want on their sites—not just spec-sheet entries. The core of each logger is a factory-calibrated NTC thermistor or Pt100 RTD, depending on the model, with a typical accuracy of ±0.5°C across the -40 to +85°C range. We stabilize the reference voltage and run multiple samples per reading so transient noise from motors or switchgear doesn’t masquerade as a temperature excursion. Memory ranges from 32,000 to 128,000 readings, enough for a three-month cold chain study at a one-minute interval. The battery is a user-replaceable 3.6V lithium cell that lasts 12–18 months in normal logging mode; the device gives a low-battery warning with about two weeks of runtime left. Start modes include push button, magnet swipe, or a scheduled time, so you don’t have to crouch inside a freezer with a laptop. Ingress protection is IP65 on most housings—they survive loading dock rain and dust without extra baggies. For labs, we offer a flat probe that fits inside vial racks and a needle probe for ultra-low freezers. The software generates PDF/CSV with min/max/mean and MKT (Mean Kinetic Temperature) automatically, and the logger stores a digital calibration certificate that travels with the data. If your project needs something unusual—a specific cable length, a high-pressure housing, or integration with a custom SCADA—our engineering team can adapt the hardware and firmware. That customization piece is why we’re deep into geotechnical monitoring; when a dam or tunnel already has our piezometers and inclinometers on a single network, adding temperature nodes takes almost no extra integration work. Worldwide distribution means you can get units and replacement probes fast, and our support engineers will walk you through setup in your local language.
