Low-Flow Calibrator Offers Easy
Operation
Two hand-held instruments from InterTech Development quickly and accurately calibrate most makes of pressure-, flow- or vacuum-type production-line leak testers.
Two hand-held instruments from InterTech Development (IDC) quickly and accurately calibrate most makes of pressure-, flow- or vacuum-type production-line leak testers, providing an easy way to maintain accurate quantitative leak data on the production line or in the laboratory The CM-25 CalMaster covers the smaller leak-rate and lower-flow calibration range of 0.025 - 1.999 sccm (standard cubic centimeters per minute), for systems testing to tighter leak- or flow-rate specifications, while the CM-15 serves the broadly typical calibration range of 0.25 - 19.99 sccm

A high-speed, low-flow leak testing instrument offers an economical air-based alternative to helium mass-spectrometer systems for QC testing of products having very low leak-rate tolerances.
Short-lead-time solves 100% leak-testing
A short-lead-time solution for 100% leak-testing of small/medium-size products or components offers custom fixtures plus programmable instrumentation and controls in a compact, modular unit.
First of their type and size in the leak-detection industry, CalMaster calibrators provide a direct and almost instantaneous reading of leakage rates traceable to NIST (National Institute of Standards and Technology) 0.2% primary standards, with repeatability of 0.05%, and display their volumetric measurements on a 3.5-digit LCD readout in half-inch (13mm) -high numerals.
Smaller, more rugged and easier to use than conventional calibration devices, including glass orifices or Bubble-O-Meters, CalMasters measure 7.5" long x 4.3" wide x 3.125" high (190 x 109 x 79mm), and weigh 1.8 lbs (820g).
Their damage-resistant design contains no delicate mechanical movements or orifices, and is rated for operation in ambient temperatures from 40§ to 105§ F (4§ - 40§ C).
Both units will accept maximum test pressures to 250 PSIG (17 bar), and maximum test vacuum to 5 psig (0.35 bar).
In use with a pressure or flow-type leak detector, the CalMaster measures air escaping from the leak detector (or leak fixture) calibration port.
Inside the instrument, the escaping air flows through a precision needle valve, across InterTech's proprietary mass flow sensor and out to the atmosphere.
Calibration of vacuum-type leak detectors is similar, with the connection being made to the CalMaster's VAC port.
CalMasters readily calibrate leak detectors with different parameters or test cycles, can be easily set to any leak or flow rate within their respective sccm ranges, and withstand 10 times over-range.
All units are shipped complete and ready to use, with all required fittings, standard 9-volt alkaline battery (which supports 50 hours of continuous operation) and carrying case.
Both models are priced around $1,400.
