Temperature Calibration Services in Walcott, ND

When accurate temperature measurements are critical, count on J&J Calibration’s temperature calibration services in Walcott, ND. We help labs, manufacturers, and food/pharma companies across North Dakota ensure their temperature-controlled equipment and sensors are precise and compliant. As an ISO/IEC 17025 accredited calibration lab, J&J offers comprehensive calibration for everything from thermometers and thermal sensors to ovens and freezers. Our North Dakota-based full-service calibration lab, part of the Accredited Labs network, provides local convenience with industry-leading expertise. Whether you’re monitoring freezer storage in Fargo or validating autoclaves in a medical facility, our trained technicians and state-of-the-art standards will keep your temperature measurements accurate across the entire thermal spectrum.

Capabilities Overview

• Wide Temperature Range: Our temperature calibration capabilities span cryogenic lows to high-temperature highs. We can calibrate sensors and devices at temperatures well below freezing (e.g. -80°C freezers or liquid nitrogen temps) up to extremely high temperatures (over 1200°C in furnaces or kilns). This broad range means we can handle precision thermometers, RTDs, thermocouples, ovens, incubators, and more, covering all your thermal measurement needs.
• Environmental Chamber Mapping: We specialize in temperature uniformity surveys and mapping for chambers like ovens, incubators, freezers, and autoclaves. Using arrays of sensors and data loggers, we can chart the temperature distribution and stability in your equipment, verifying it meets FDA, USDA, or ASTM mapping requirements. For example, we provide oven mapping and refrigerator/freezer mapping services to ensure those chambers hold the setpoints and uniformity your process requires.
• Precise Reference Standards: J&J uses high-accuracy reference thermometers (SPRTs, PRTs), dry-block calibrators, liquid calibration baths, and digital thermometer readouts that are all NIST-traceable. These allow us to calibrate your temperature devices with uncertainties often in the tenths of a degree or better. Our ISO 17025 accredited procedures cover various sensor types (thermocouple types B, E, J, K, N, R, S, T, etc., and RTDs) and we can simulate or measure temperature points relevant to your operations. We also handle humidity calibrations for hygrometers and humidity chambers, using calibrated humidity generators for accurate RH readings.
  
  

Equipment Types Serviced

We provide calibration for a broad spectrum of temperature measuring equipment, including:

• Thermometers: Digital thermometers, glass stem thermometers, and high-precision reference thermometers. This covers handheld temperature probes, thermistors, and IR thermometers (infrared temperature guns). We ensure each reads true against our standards at multiple test points (e.g. 0°C, 100°C, etc.).
• Thermocouples & Sensors: All common thermocouple types (J, K, T, E, R, S, N, etc.) including wired probes and thermocouple calibration sets. We calibrate surface probes, immersion probes, and air temperature sensors. In addition, we calibrate RTD probes (Pt100, Pt1000) and thermistors, verifying their resistance-temperature correlation and adjusting readouts as needed.
• Temperature Controllers & Data Loggers: Temperature chart recorders, digital data loggers, and thermostat/controllers used in ovens or HVAC systems. We test their readings and outputs over their operating range. For data loggers, we can perform multi-point calibrations and provide before/after calibration reports, so you know the correction at each measured point.
• Environmental Chambers: Ovens, incubators, freezers, furnaces, autoclaves and other temperature-controlled chambers. We not only calibrate the built-in temperature displays/controllers, but can also perform full spatial uniformity mapping. For instance, we calibrate autoclaves by placing calibrated thermocouples throughout the chamber to verify sterilization temperatures. Refrigerators/freezers are tested at various locations to ensure all products are within safe temperature.
• Miscellaneous Equipment: Dry-well calibrators and temperature baths (to ensure they provide accurate set temperatures for your own calibrations), thermal cameras (checking their temperature reading accuracy against blackbody sources), and humidity meters/psychrometers (verifying temperature/RH sensing).

Accreditation & Standards Compliance

Our temperature calibration processes are ISO/IEC 17025:2017 accredited, meaning they meet rigorous international standards for technical competence. We are equipped to meet ANSI/ASTM standards relevant to temperature calibration (such as ASTM E220 for thermocouples, or FDA guidelines for equipment qualification in pharma). All calibrations are traceable to NIST – we use standard reference materials and calibrated devices that link unbroken to national standards. The result is a calibration certificate you can trust: it will detail the equipment’s performance (error at each test point), the uncertainty of measurement, and traceability references. This documentation ensures audit readiness for ISO 9001, FDA/USDA inspections, and other regulatory audits. We also help you remain compliant with any required re-calibration intervals, offering reminders and an online certificate management system so you never miss a due date. J&J’s emphasis on quality and consistency means you get reliable calibration every time – so you can have total confidence in every temperature reading.
