PTC Professional Temperature Calibrator
The PTC Series portable temperature calibrator matches lab features-like a wide temperature range, high accuracy, stability, and speed—with-our well-known, long-lasting quality in a single industrial calibrator. Three temperature calibrator models are available, from the basic unit to a full model, including signal inputs and external reference sensor.
CTC Compact Temperature Calibrator
The CTC Series portable temperature calibrator is a fast, timesaving, reliable dry block temperature calibrator designed for on-site use. The large, easy-to-read color display provides icons and information regarding the status of the calibrator and the calibration in process. Popular functions like automatic switch test and auto-stepping are available with special one-key/one-function buttons.
MTC Marine Temperature Calibrator
The MTC Series portable temperature calibrator is a fast, timesaving, cost-effective calibrator designed specifically for the maritime industry. Maximize accuracy with a one-year recommended calibration interval or lower the cost of ownership of your temperature calibrator by extending the interval to three years! Reduce costs associated by recalibration and managing assets by 66%.
ETC Easy Temperature Calibrator
The ETC Series is the ideal dry block temperature calibrator when time is the critical factor and the highest accuracy is not a requirement. The block heats up to 100°C per minute and stabilizes in just three minutes! The small size and lightweight design fit perfectly in a tool box, making it the perfect field calibrator to verify sensors in hard-to-reach places
Rugged construction, featuring stainless steel and rubber side panels, make the instrument suitable for many years of service in an industrial environment.
We provide the world’s only ball-type dead-weight testers in which the ball and weights float on a thin film of air, making them virtually frictionless. This design eliminates the necessity to rotate the weights during testing and allows the user to concentrate on the instrument itself. Our testers are engineered to offer user-friendly, safe operation in the field or in a lab. Both pneumatic and hydraulic dead-weight testers are available.
PK II Dead-Weight Tester
The PK II floating ball-type pneumatic dead-weight tester is engineered to offer user-friendly, safe operation. The easy-to-use primary standard provides reliable and accurate pressure measurement in the field or in the lab.
RK Deadweight Tester
The RK floating ball-type pneumatic dead-weight tester is engineered to offer user-friendly, safe operation. The easy-to-use primary standard provides reliable and accurate pressure measurement in the field or in the lab.
HK Dead-Weight Tester
The HK floating ball-type pneumatic dead-weight tester is engineered to offer user-friendly, safe operation. The easy-to-use primary standard provides reliable and accurate pressure measurement in the lab.
HL Dead-Weight Tester
The HydraLite Tester is a primary standard available as a dead-weight tester or a gauge. Both feature a re-entrant-type measuring piston and cylinder assembly. This design reduces the rate of fluid leakage and increases float time, helping to maintain accuracy as test pressures increase. Each tester features an easy-to-use, convenient screw pump as the pressure source, which contains a ratchet feature that prevents the unit from depressurizing unexpectedly.
Type T Dead-Weight Tester
The Type T tester is a dead-weight tester that offers laboratory accuracy in an instrument designed to withstand an industrial environment or the daily stresses of a manufacturing environment. Each tester features a re-entrant-type measuring piston and cylinder assembly. This design reduces the rate of fluid leakage and increases float time, helping to maintain accuracy as test pressures increase.
Our pressure calibrators offer a wide variety of features, accuracies, and pressure ranges. Included are intrinsically safe percent-of-reading calibrators, reference-data recorders, wide-range dualsensor calibrators, and calibrators with built-in pressure pumps. Many of our calibrators also offer current measurement, voltage measurement, 24-volt-loop power supplies, and even complete systems with pressure pumps and calibration software. In many cases, one handheld pressure calibrator can replace multiple instruments, reducing ongoing recalibration and maintenance costs.
HPC50 Series Pressure Calibrator
The HPC50 handheld pressure calibrator is an intrinsically safe, dual-pressure calibrator with options to add an additional two external-pressure or temperature modules. The HPC50 pressure calibrator combines the features you love from the HPC40 with improvements like better battery life, an improved display, an extra external-module connection, and of course intrinsic safety.
HPC40 Series Pressure Calibrator
The HPC40 Series handheld pressure calibrator is the world’s first combined pressure and mA loop calibrator to be fully temperature compensated from -20°C to 50°C. You can count on the same accuracy whether measuring pressure, current, voltage, or temperature.
nVision Reference Recorder
Accurate enough to replace a dead-weight tester; rugged enough to sit in three feet of water–the nVision Reference Recorder is portable enough to complete calibrations anywhere!
30 Series Pressure Calibrator
The 30 Series is a wide-range digital pressure calibrator that fits easily into your shirt pocket. Its internal sensors give you 0.05% of reading accuracy and resist damage from overpressure.
CrystalCalHP Calibration System
This portable gauge and transmitter calibration system is seven to 10 times faster than a dead-weight tester. It allows you to do a 10-point up and down calibration in less than three minutes, including printing out a calibration certificate.
APM CPF Series Pressure Module
The APM CPF Series portable pressure modules offer the functionality and flexibility to perform pressure calibrations with a multifunction process calibrator. Or, combine it with a hand-held pressure calibrator to expand its range. The APM CPF delivers the same high-level accuracy whether in the lab or in the field.
APMi Intrinsically Safe Pressure Module
The APMi intrinsically safe portable pressure modules offer the functionality and flexibility to read up to four pressure inputs with a single HPC50 handheld pressure calibrator. Use the modules to either expand the range of the HPC50, view all four readings at the same time, or read two different differential pressures simultaneously. The APMi intrinsically safe pressure modules deliver the same high-level accuracy whether in the lab or in the field.
Multifunction Process Calibrators
Our multifunction process calibrators read and source RTD, thermocouple, current, voltage, frequency, and resistance to calibrate or verify your process sensors. They can also be combined with APM CPF pressure modules to calibrate pressure, or a dry-block calibrator to calibrate temperature. The multifunction handheld ASC-400 calibrator features a large, full-color display with an advanced-simplicity, easy-to-use interface.
ASC-400 Multifunction Calibrator
The ASC-400 combines all your favorite features such as percentage-error calculation, scaling, leak-testing, and switch-calibrating into one multifunction process calibrator.
