Handheld Temperature Instruments – mobile, precise & versatile
Handheld temperature meters are the flexible solution for service, maintenance, QA and validation—from HVAC/buildings to food/HACCP, pharma/labs, and machine & plant engineering.
Depending on the task they use RTD sensors (Pt100/Pt1000), thermocouples (Type K/J/T/N), or infrared (IR). Features like multi-channel, Min/Max/Hold, logging, alarms and interfaces (USB/Bluetooth/Modbus) simplify documentation and data transfer.
ICS Schneider Messtechnik supports sensor/instrument selection, calibration (ISO/DAkkS), validation, and HACCP/GMP-compliant documentation.
FAQ on Handheld Temperature Instruments
Answers on sensors, accuracy, probes, IR measurement, logging, calibration, HACCP/GMP and integration.
Which sensor types are supported?
| Sensor | Range (typ.) | Advantages | Use |
|---|---|---|---|
| RTD (Pt100/Pt1000) | −200…+600 °C | very accurate, stable | QA/lab, reference |
| Thermocouple (K/J/T/N) | −200…+1 200 °C | robust, fast | service/process, high T |
| IR (pyrometer) | −50…+1 000 °C (typ.) | non-contact, fast | moving/delicate surfaces |
How accurate are handhelds?
Typically ±0.1…0.3 K (RTD) or ±0.5…1 % of reading / ±1…2 K (TC/IR)—depending on instrument, sensor, calibration and ambient conditions.
What probe types are available?
| Probe | Properties | Typical use |
|---|---|---|
| Immersion | sealed, slim | liquids, baths |
| Surface | flat tip | plates, pipes |
| Air/gas | perforated sleeve | room/duct |
| Needle penetration | pointed, robust | food core temperature |
| Magnetic/clamp | quick to mount | pipes/machine surfaces |
IR or contact—what’s better?
IR is fast/non-contact but emissivity-dependent. Contact is robust and traceably more accurate with proper coupling. Often a combination is ideal.
How does response time affect results?
Small probe diameters and good thermal coupling (paste/contact pressure) shorten t63/t90. For IR, the D:S ratio and focus are key.
What does D:S (IR spot size) mean?
Distance-to-spot determines the spot size. The spot must be fully covered by the target, otherwise readings are biased.
Are multi-channel handhelds available?
Yes, 2–4 channels are common (e.g., 2×TC + 2×RTD). Running different probes in parallel supports comparison and validation.
Which functions are important for QA?
Min/Max/Hold, averaging, offset/adjustment, time stamp, alarms, and a logger with export (CSV/PDF).
How does data logging work?
Via internal memory or app/PC software. Typical intervals 1 s…60 min, export via USB/Bluetooth; optional cloud upload.
Food/HACCP—what should I consider?
Use fast penetration probes, smooth/easy-to-clean housings (IP rating), documentation with time/user, and calibration labels.
GMP/pharma—how to ensure valid measurements?
Select instruments with traceable calibration, tamper-proof reports, user/audit functions and a clear measurement chain.
How often should I calibrate?
Rule of thumb annually; for critical applications semi-annually or after shock/overheat. Store certificates in a revision-safe way.
Can I adjust offsets?
Many instruments allow a 1-point offset or multi-point adjustment. Document and seal changes (QA).
What IP ratings/form factors exist?
Handhelds typically IP54…IP67. Rubber guards, bumpers and hands-free mounts improve field usability.
Rechargeable or battery-powered?
Both exist. Check runtime, charge time, auto-off, and spare batteries for field work.
Typical sources of error?
- Poor coupling → improve paste/contact pressure
- Wrong ε (IR) → set emissivity, add matte reference spots
- Heat bridges → insulate, avoid drafts
- Wrong spot size → observe D:S
How do I link the handheld to software?
Via USB, Bluetooth or RS-485/Modbus. Export as CSV/PDF; integrate into SCADA/cloud via a gateway.
Are pre-configured sets useful?
Yes: instrument + matching probes (e.g., air/surface/penetration) + calibration saves time and prevents mis-purchases.
Do you support selection & validation?
Yes. We advise on instrument/probe, provide calibration certificates, help with IR setup (ε/D:S) and with logging/report configuration.
Can handhelds measure differential temperature (ΔT) or averaging?
Many multi-channel models offer ΔT between probes and statistical functions (mean/min/max). Useful for heat-exchanger checks, validation and trend analysis.
