Remotely record temperature, humidity, and dew point up to 10 feet from the display and set the alarm to sound and flash the display if temperature readings rise above or fall below a set range. This recorder has a remote probe on a 10-ft. cable and a display that can be set to show current temperature, minimum/maximum temperature, or relative humidity and calculated dew point. Charts (not included) are required; select a recording time and temperature range from the available chart options.

About half the size of standard temperature chart recorders, these are often used to monitor temperature inside refrigerators, incubators, storage compartments, and other small spaces. They have a built-in sensor, so no probe is needed. Charts (not included) are required; select a recording time and temperature range from the available chart options.

Record temperature in hard-to-access areas. These recorders have a remote thermocouple type-J probe on a 15-ft. cable. They include 60 assorted charts with a variety of recording times and temperature ranges.

Note: Thermocouple probes are not interchangeable with RTD probes.

To alert you of temperature fluctuations, these recorders sound an alarm and flash the display when temperature rises above or falls below the programmable temperature range. They have a thermocouple type-K probe on a 4-ft. cable for taking readings in hard-to-access areas. Charts (not included) are required; select a recording time and temperature range from the available chart options.

Note: Thermocouple probes are not interchangeable with RTD probes.

Probe extension cable extends the probe's reach by 10 feet.

No cords or software required—these data recorders store readings on an included SD card in Excel format for easy transfer to a PC.

Data recorders with a NIST certificate of calibration include a calibration certificate traceable to NIST that states the recorder has passed a test for accuracy.

Monitor temperature and pressure in hard-to-access system components with this data recorder that has remote sensors that track and store readings for upload to a PC. It requires software and a USB cord (not included).

Measure and store up to 8,800 temperature readings from two sources and upload the data to a PC.

Store up to 500 readings on these thermometers and determine temperature within ±0.75° F accuracy.

Thermometers with NIST certificate include a calibration certificate traceable to NIST that states the thermometer has passed a test for accuracy.

The optional type K probe (sold separately) connects to your thermometer to measure temperatures up to 537° C or 1000° F.

For more accurate and consistent readings than thermometers with thermocouple probes and a longer service life, this thermometer has a resistance temperature detector (RTD) probe. It logs up to 2,000 time- and date-stamped readings and uploads data to a PC through the USB port.

To conserve battery life, use the optional power adapter (sold separately).

For comprehensive system checks and quality control, these meters measure a wider relative humidity range than pocket meters and can determine dew point in addition to humidity and temperature.

Identify intermittent issues such as voltage spikes and temporary power flow problems—this meter records measurements from electrical tests over time. Review data in real-time or save it for future analysis.

This true RMS multimeter takes accurate AC measurements regardless of the load type or sine wave shape. This is important for testing electronic devices that draw current in short pulses that can distort the shape of the wave, such as computers and adjustable-speed drives.

Display count is an industry designation and not an actual value. This 6,000-count multimeter shows numbers up to 5,999.

Measure temperature, humidity, and radiant heat in your work area to keep your team safe from heat-related hazards. These monitors help you avoid dangerous conditions and comply with OSHA standards for a safe work environment. They use a variety of measurements from your surroundings to calculate the heat stress index and the wet bulb globe temperature (WBGT), which tell you how hot it feels. Set a maximum wet bulb globe temperature, and an alarm will go off when heat reaches the safety limit.

These monitors have two sensors. One measures temperature, humidity, dew point, and wet globe temperature. The other measures black globe temperature, which is the effect of direct solar radiation on an exposed surface. Carry monitors with you to measure different areas, or mount to your tripod to measure conditions over time.

To maintain their accuracy, monitors should be calibrated once a year. You can calibrate the monitor yourself using humidity standards. These standards contain a known humidity, so you can adjust your monitor until it reads the humidity correctly.

Monitors that come with a calibration certificate traceable to NIST have passed a test for accuracy.

Power these monitors with the included batteries, or add a power adapter to plug them in.

Add a memory card to store your readings and export them to a computer.
