Calibration equipment standards cover a range of jobs, from verifying a single null reading to logging 16 thermocouple channels. The listed prices here spread from $49.00 to $2,999.99, which means the first decision is not brand preference but what kind of signal you need to check. If your work is pressure calibration, you will likely end up with a different unit than if you are monitoring temperature across multiple points.
Quick Take
- For pressure calibration, the Fluke 719Pro 300G is the dedicated pressure calibrator in this set, with the 719Pro-300G model naming.
- For multi-channel temperature logging, the Applent AT4116 accepts J-, K-, and T-type thermocouples across 16 channels.
- For bench-level null and calibrator work on a budget, the B&K 750 is a wired used unit that powers on but is not otherwise tested.
- For a temperature indicator repair or parts candidate, the Thermo Electric 311600 Digi-Mite is listed for parts or repair.

Product Notes
Thermo Electric 311600 Temperature Calibrator Indicator Digi-Mite [A1B1
This Digi-Mite is a temperature calibrator indicator from Thermo Electric, with the MPN 311600 and Country of Origin China. It is sold for parts or repair, which makes it a project rather than a ready-to-use reference. The useful angle is if you already have a test setup and want a specific Digi-Mite body to repair or harvest. The main limitation is that no working condition is confirmed, so it should not be your only standard for any measurement you depend on.
B&K 750 Test Equipment Calibrator Null Indicator | POWERS ON UNTESTED
The B&K 750 is a used, wired test equipment calibrator and null indicator with a blue finish. It powers on, but the listing says no other tests have been performed, so you are getting an unknown calibration state. Choose it when you want the lowest listed price in this group and can run your own checks before relying on it. The limitation is that the unit shows scratches and imperfections from age, and the functional confidence stops at the power-on light.
Fluke 719Pro 300G Electric Pressure Calibrator 719Pro-300G 719 Pro
The Fluke 719Pro 300G is a used electric pressure calibrator, carrying the 719Pro-300G model number. The listing states it is in great working and cosmetic condition, was pulled from the field due to an upgrade, and comes with only what is pictured. This is the option to choose when your work is pressure calibration and you want a dedicated Fluke unit without buying new. The limitation is the significantly higher listed price and the fact that it is calibrator-only, so the pictured contents define what you get.
Applent AT4116 16-Channel Thermocouple Temperature Meter Data Logger Kit
The Applent AT4116 is a new open-box temperature meter and data logger kit with 16 channels for J-, K-, or T-type thermocouples. The description includes a color TFT display, high/low alarms, broken-thermocouple detection, USB storage, and RS-232 communication. Pick this one when you need simultaneous multi-point temperature measurement rather than pressure calibration. The limitation is that it only works with temperature inputs and is open box, so the original packaging has been opened and the included accessories are what is supplied.
Final Recommendation by Use Case
- If you need electric pressure calibration, choose the Fluke 719Pro 300G.
- If you need multi-point temperature data logging, choose the Applent AT4116.
- If you want a low-cost bench null indicator and can perform your own checks, choose the B&K 750.
- If you need a Digi-Mite temperature indicator for a parts or repair project, choose the Thermo Electric 311600.
