About This Product
Designed for polytechnic and engineering college laboratories, this Lab Meters instrument is housed in a wooden box and read against its mirror scale to avoid parallax error.
Frequently Asked Questions
Q1. What does the anti-parallax mirror do? The mirror behind the knife-edge pointer lets the user line the pointer up with its reflection, so the reading on the 144 mm scale is taken without parallax error.
