The difference between Full-closed and Semi-closed:
Semi-closed: no backcover, from the back "can see" components on the circuit board; viewing area: 51*24.5mm; font: 19*9mm
Full-closed:with a backcover, from the back "can not see" components on the circuit board; viewing area: 61*24.5mm; font: 21*11mm
Features:
Two-wire direct measurement without working power.
display with blue backlit.
Product stability is good, high precision measurement, anti-interference ability.
The appearance of the standard size, easy installation.
