Product Introduction
TA-272-3P is a compact, portable, on-site calibration tool for watt-hour meters that can be used for accuracy verification, online power energy monitoring, and pulse sensing. It can identify abnormal working conditions like leaks, theft, and other issues swiftly. The goal of the TA-272 Series is to solve the issue of device portability and give electricians more effective working conditions.
Actually See Your Result
Put your data down in black and white. Although our terminal is convenient enough to detect, sometimes you will face the situation where there are many sets of data needing to be looked at. By connecting the terminal with a printer, you can easily do so, and it's configurable and printable on the spot.
Wider Measurement Range
It has a wider measurement range. There is an extra wide measurement range for current and voltage. TA - 272 - 3P can measure a wide range of current with a 500:1 range to ensure accuracy. The current display range is 10000:1 with a 1mA minimum start - up current, and it also supports high voltage metering.
We Are the All-Mighty
Our capability may outdo your imagination. TA - 272 - 3P can meet your regular testing parameter needs and be able to configure with a printer. Moreover, for meters with no pulse, TA - 272 - 3P can run electric energy accumulation.
Support Customization
It supports customization. It offers competitive prices, ensures timely delivery, has a good reputation, provides 24 - hour response, a 12 - month warranty, continuous product upgrades, permanent technical support, customization services, and OEM/ODM services. It also supports color customization, cable length customization, and logo customization.
