Description
Topcon AT-B2 32X Auto Level — High-Precision Optical Levelling
The Topcon AT-B2 is the high-precision model in Topcon's AT-B auto level range, with 32x magnification and ±0.7 mm per km double-run accuracy (±0.5 mm with optional micrometer). It's built for surveyors, engineers and civil contractors doing precise levelling on roads, drainage, earthworks and large concrete pours. The magnetically damped compensator settles fast and stays stable near heavy plant, the 2-speed focus knob makes fine adjustment easy, and the IPX6 sealed body keeps working in heavy rain.

Frequently Asked Questions
Who is the AT-B2 designed for?
The AT-B2 suits surveyors, engineers and civil contractors who need higher accuracy over longer sight lines, such as road, drainage and earthworks levelling. For general building work, the AT-B3A or AT-B4 is usually enough.
What is the difference between the Topcon AT-B4, AT-B3A and AT-B2?
The AT-B4 has 24x magnification for general building work. The AT-B3A has 28x and ±1.5 mm/km accuracy. The AT-B2 is the precision model with 32x magnification, a larger 42 mm lens, 2-speed focus and ±0.7 mm/km accuracy.
What is the micrometer option?
An optional parallel-plate micrometer attachment improves accuracy to ±0.5 mm per km double run for precise levelling work.
Does it come with a tripod and staff?
No. The kit includes the level, hard case, cover, lens cap and tools. Pair it with the Topcon heavy duty flat head tripod and a levelling staff such as the Topcon 7 m E-face staff.
How often should an auto level be checked?
We recommend an annual service and calibration check, plus a quick two-peg test on site if the level has been knocked. For service, contact Topcon Australia on 1300 965 273; there are service and calibration centres in Sydney, Brisbane, Melbourne, Perth, Adelaide, Darwin, Canberra and Hobart.
What warranty does the AT-B2 have?
Topcon Australia gives new auto levels a 5-year limited warranty from the date of purchase. Keep your proof of purchase, as damage from drops or misuse is not covered.
