humidity and temperature data loggers

Humidity and temperature data loggers from Kingmach give engineers and technicians a practical way to capture environmental data on site without spending a lot of time on configuration. The standard measurement range covers -40°C to 85°C for temperature and 0 to 100% RH for humidity, with accuracy typically around ±0.3°C and ±3% RH. These specifications meet the demands of most structural health monitoring, slope stability studies, and environmental baseline surveys. Each logger stores several hundred thousand data points—enough for months of recording at 10-minute intervals—and the non-volatile memory keeps readings safe even if the battery drains completely. Users can set the logging rate from once per second up to once every 24 hours, depending on how granular the data needs to be. Many models come with an LCD display that shows current readings, battery status, and memory usage, which saves time during site visits. The built-in keypad lets you start or stop logging without a laptop. For connectivity, loggers commonly include a USB port and sometimes RS-485, which makes it easy to pull data or hook into a Modbus network. The software runs on Windows, and it handles device setup, data download, and basic charting. You can export records as CSV or PDF, and you can set separate alarm thresholds for temperature and humidity. When a reading goes outside the limit, the logger flags the event in the file and, on some models, triggers a visual alert. Kingmach offers these data loggers with a choice of internal or external sensors. External probes come in rigid or flexible cable variants, with lengths specified at order time. This flexibility helps when the logger must stay in a weatherproof box while the sensor reaches into a borehole or behind a panel. Enclosures are typically IP65 or higher, made of polycarbonate or aluminum, and designed to handle rain, dust, and wide temperature swings. Wall-mount brackets and lockable hasps are standard. Because every site brings its own constraints, Kingmach’s team can adjust sensor calibration ranges, cable connectors, or logging firmware to match the job. They also keep stock in several regional warehouses, so standard units can ship within days, not weeks. For engineers who need to monitor more than one location, the same software can manage multiple loggers simultaneously, letting you compare data from different points in a single view.
