Explore our range of high-precision RTD thermometers, engineered for accurate temperature measurement in industrial, laboratory, and field environments. Our selection includes waterproof handheld devices, dual-input models, and high-resolution instruments compatible with PT100, PT500, PT1000, and Ni1000 sensors. Ideal for food processing, pharmaceutical manufacturing, HVAC, and environmental monitoring, these thermometers deliver IP67-rated protection, dual displays, and optional datalogging to meet the most demanding measurement requirements.
RTD (Resistance Temperature Detector) thermometers offer superior accuracy and long-term stability compared to thermocouple-based instruments, making them the preferred choice for precision measurement applications. An RTD thermometer works by correlating the resistance of a metal element — most commonly platinum — with temperature. The PT100 sensor (100 ohms at 0°C) is the international standard for industrial and laboratory temperature measurement, while PT1000 and Ni1000 variants offer higher sensitivity and are ideal for HVAC, building automation, and process control.
Key advantages of RTD thermometers include measurement accuracy to ±0.1°C or better, excellent repeatability over wide temperature ranges, compatibility with a broad range of probe types, and resistance to electrical noise in industrial environments.

Choosing between a PT100 and PT1000 thermometer depends on your application, cable lengths, and sensitivity requirements. PT100 sensors are the most widely used in industrial process measurement, offering robust performance over long cable runs and compatibility with the widest range of instruments. PT1000 sensors deliver ten times the resistance, making them significantly less sensitive to lead resistance errors — ideal for HVAC, laboratory instruments, and installations where cable length is a concern.
Our range includes dedicated PT100 meters, PT1000 thermometers, and multi-sensor instruments that support PT100, PT500, PT1000, and Ni1000 probes in a single handheld device.
An RTD thermometer is the handheld or benchtop display instrument — the device you read the temperature from. It works together with (but is a different product to) an RTD probe or sensor, the physical Pt100/Pt1000/Ni1000 element that goes into the process, vessel or material being measured.
Looking for a replacement or custom-length sensor rather than a display instrument? See our RTD Probes range.

When selecting an RTD thermometer for your application, consider the following specifications:
An RTD (Resistance Temperature Detector) thermometer measures temperature by detecting changes in electrical resistance in a platinum sensing element. It is widely used in industrial and laboratory environments for its accuracy, stability, and compatibility with international standards such as IEC 60751.
Both are platinum RTD sensors, but PT100 has a resistance of 100 ohms at 0°C while PT1000 has 1000 ohms. PT1000 sensors are more sensitive to resistance changes, making them less susceptible to lead resistance errors and suitable for HVAC and laboratory applications.
Yes. Models such as the CENTER 370 and 372 carry IP67 waterproof ratings and meet the requirements for HACCP-compliant temperature verification in food processing environments.
Yes. Pacific Sensor Tech operates a NATA-accredited calibration laboratory. We offer both in-house and on-site calibration services for RTD thermometers to ISO 9001:2015 standards.
Yes. Many instruments in our range, such as the CENTER 375 and Comet D0221, are compatible with multiple sensor types including PT100, PT1000, and Ni1000 probes.
