When engineers and instrumentation technicians need reliable portable process calibrators for workshop bench testing, or live plant environments, Instrotech’s locally designed and manufactured Calog calibrators range, including the 4-20 mA Loop Calibrator, delivers.
Built around modern component technology, an intuitive interface, and a rugged IP54-rated housing, the Calog series is engineered for the demands of real industrial field calibration work.
All Calog calibrators offer a consistent set of key features, providing the same practical tools for engineers regardless of the specific model:
• Key-per-digit numeric entry for fast source value setup – scroll each digit independently up or down without cycling through the full range.
• 128 x 64 backlit LCD display – switchable between numeric or trending views with programmable timing.
• Data-logging via SD card or USB – download to a PC and open in spreadsheet software.
• Compact and rugged – 86 x 155 x 43 mm, IP54 rated for dust and splash resistance.
• Lithium-Ion battery with approximately 8 hours of run time (measured and sourced combined), with temperature sensing built in.
• Programmable auto-off and selectable date/time settings.
• Standard accessories included: battery charger, carry case, non-slip rubber cover, and safety leads.
• 2-year guarantee against faulty materials and workmanship.
The Calog-TEMP is a high-precision, multifunctional temperature calibrator that handles the full range of temperature measurement and sourcing tasks in a single handheld device. It measures milliamps, millivolts, thermocouples, ohms, and RTDs simultaneously. Temperature channels are isolated from the mA channel so both can be displayed at the same time.
The Calog-LOOP II, now in its second generation, is purpose-built for milliamp loop-powered instrumentation. It measures, sources, and simulates 4-20 mA signals with an accuracy of 0,01% full scale (0-24 mA input range) and 0,005% full scale for 0-32 V inputs. Sourcing modes include increment, step, ramp, and valve stroking – useful for commissioning and fault-finding on control valves and transmitters. DC voltage (0-32 V) and circuit continuity measurement are also included.
The Calog-PRESSURE II is a second-generation portable pressure calibrator that combines pressure measurement with the full capabilities of an mA loop calibrator. This makes it a single instrument for pressure transmitter calibration, I/P converter testing, and general loop maintenance.
The Calog-LC II is Instrotech’s most feature-complete portable calibrator, designed specifically for strain gauge load cell testing, diagnostics, and calibration. It supports indication and data logging via USB or an SD card. A key benefit of the Calog-LC II is in situ load cell testing – no need to remove the load cells. Each cell can be tested and a diagnostic readout obtained in under ten seconds.
