Helpful Buying Guide

Choose a thermometer for the way you measure and monitor

Start by deciding whether the task calls for a quick handheld reading, a non-contact surface check, ongoing temperature and humidity records, or temperature control. Then compare the measurement method, available range, data functions, alarms, probe compatibility, and placement options that fit the work.

Use Cases

Match the instrument to the task

Use infrared thermometers for non-contact surface checks during maintenance, inspection, and facilities work. Choose fold-up, stem, or RTD instruments for contact temperature checks. Select data loggers and wall monitors when ambient temperature or relative humidity must be reviewed over time or at a glance.

How to Choose

Compare measurement method and range

Consider whether you need infrared, contact-probe, RTD, thermocouple, or ambient measurement. Compare stated maximum or operating ranges where provided, such as infrared models up to 630°F or 1200°F, a fold-up probe to 572°F, and a digital stem range of -40 to 450°F.

Applications

Support monitoring, inspection, and control

Available tools support facility, HVAC/R, warehouse, greenhouse, museum, environmental monitoring, foodservice, medical, pharmaceutical, industrial, research, educational, and heating-process applications. Temperature and humidity data loggers are suited to unattended environmental tracking, while PID control supports heating applications.

Additional Information

Look for data and placement features

For documented monitoring, compare storage capacity, sampling intervals, computer connection, timestamps, and alarms. Options include up to 16,000 readings for each measurement type, 32,000-reading storage, adjustable sampling from as often as 1 second or 2 seconds up to 24 hours, USB transfer, wall-mount hardware, and secured mounting features.

1200°FMaximum infrared range

One mini infrared thermometer supports readings up to 1200°F.

32,000Stored readings

Selected temperature and humidity loggers provide 32,000-reading storage.

1 secondShortest stated sampling interval

One logger allows schedules from 1 second to 24 hours.

14 to 122°FWall monitor temperature range

The digital wall monitor measures temperature across this stated range.

Planning Guide

Plan the right fit before choosing

Handheld measurement

Select contact or non-contact temperature checks

Infrared thermometers provide non-contact surface readings and may include laser pointers for aiming. Some models add a Type K input, ambient temperature display, programmable alarms, and max/min/average/difference functions. Contact options include adjustable-probe pocket thermometers, digital stem thermometers, and RTD instruments with compatible probe support.

  • Choose a laser-equipped infrared model for targeted surface measurements.
  • Choose a fold-up probe with adjustable positions for angled or tight spaces.
  • Choose an RTD instrument when compatible PT-100, PT-500, or PT-1000 4-wire sensors are required.
  • Consider display, data hold, min/max, average, or relative functions when readings need review.
Environmental monitoring

Plan for live checks or recorded condition history

Wall monitors display ambient temperature and relative humidity together, while data loggers capture conditions for later review. Logger choices include USB connection, removable SD card recording, configurable high and low thresholds, visible alarm indicators, software-supported review, and date and time stamps.

  • Compare temperature-only needs with combined temperature and humidity monitoring.
  • Match sampling intervals to the monitoring schedule.
  • Consider storage capacity for extended tracking.
  • Choose wall-mount hardware, a mounting bracket, or a lock when fixed placement is needed.
Temperature control

Choose control functions for heating processes

A digital PID controller is intended for heating applications that require temperature regulation. It supports thermocouple and RTD inputs, a single relay output, soft-start operation, and ramp-and-soak programming for controlled temperature changes.

  • Use PID control where reducing overshoot, fluctuations, and drift is important.
  • Check sensor input compatibility before selecting a controller.
  • Consider ramp-and-soak programming for planned heating sequences.
  • Review included mounting and wiring components for installation needs.
FAQ

Common questions before buying

What is the difference between infrared and contact thermometers?

Infrared thermometers support non-contact surface temperature checks. Contact thermometers use a probe, stem, or compatible RTD sensor for temperature measurement.

Which products record temperature and humidity over time?

Temperature and humidity data loggers record environmental conditions for later review. Available features include USB download, adjustable sampling intervals, storage, alarms, and mounting options.

Can these tools monitor humidity as well as temperature?

Yes. Digital wall monitors and selected data loggers display or record both ambient temperature and relative humidity.

What features help with heating-process control?

The digital PID controller provides fuzzy logic PID control, thermocouple and RTD inputs, a single relay output, soft-start operation, and ramp-and-soak programming.
