Overview
GAOTek Advanced Multifunction Temperature and Signal Calibrator is a portable field calibrator powered by a large-capacity high-performance polymer rechargeable battery. It can be connected to an external pressure module. It is easy to operate, powerful, stable, and highly accurate. It is very cost-effective. High thermal comprehensive calibration instrument.
Features
- It can output V, mV, mA, Ω, and also can simulate thermocouple or thermal resistance signals;
- It can measure V, mV, mA, Ω, pressure, and calibrating pressure switch, and also can use a thermocouple or thermal resistance signals to measure temperature;
- Measurement and output can be carried out at the same time, and mutually separated;

- High-definition display screen, favorable human-machine interface, full-Chinese operation interface;
- It supports step output, and can automatically program commonly-used step signals and step intervals, and it supports two modes of automatic steps and manual steps;
- It adopts a Pt100 temperature measurement probe for cold-end temperature compensation, and supports two modes of ambient temperature tracking and constant temperature setting, which will facilitate use;
- With multi-function and programmable unit conversion function, it can converse V, mA output or measurement signals into other units such as °C, °F, %, kPa, MPa, psi, mmHg, mmH₂O, m³/s, m³/min, m³/h, L/s, L/h, L/min, m, ?;
- When outputting mA signals, it supports two modes of mA source and simulation transmitter;
- When outputting and measuring thermocouple °C signal, it displays corresponding mV value;
- When outputting and measuring thermal resistance °C signal, it displays corresponding Ω value;
- When outputting and measuring Ω signal, it supports two-, three-, and four-line modes;
- It provides 24V DC loop source, and measures mA signals in the loop;
- It can conduct signal fine-tuning at any digit of output value;
- When measuring values, it can lock or unlock measurement values;
- When measuring values, it can collect minimum and maximum values, and calculate mean value.
