Levelling Instruments

An Auto Level is a Professional Leveling Tool used by Contractors, Builders, Land Surveying Professionals, or the Engineer who demands accurate leveling every time. AutoLevels set up fast, are easy to use, and save time and money on every job. Auto-Levels are great for Fence Builders, Foundation Installers, Deck Builders, Landscaping Pros, Swimming Pool Builders, Home Builders, Roadwork Jobs, Excavations and More. Auto Levels require that you level the instrument by hand, but you’re only required to get the bubble within the black circle on the bubble vial, from there the internal compensator takes over and precisely levels itself. Easier to Level, Quick to Level, and Greater Accuracy.

Total Station

Opti-cal Survey Equipment has been supplying precision measurement technology to surveyors for the past decade, and with service and distribution partnerships with Leica Geosystems, FARO Technologies and SPX Radiodetection, we are fast becoming the number one choice in the UK and Ireland for survey professionals to source their instrumentation.

Whether you are looking for Lasers and Levels, Total Stations, GPS kit or state-of-the-art 3D Laser Scanners, you will find it all here.

Etrix GPS

Global positioning system (GPS) receiver continuously tracks and uses up to 12 satellites. Calculates current and average speed, time of sunrise and sunset, trip distance, and more. Automatic track log--10 saved tracks let you retrace your path in both directions. Tough waterproof case; runs for 18 hours on 2 AA batteries. Compatible with optional Garmin MapSource software for downloading trip and waypoint data (not map compatible).


The MSK beacon receiver provides superior weaksignal performance, allowing differential corrections to be received at long distances from the reference station and during challenging weather conditions. The dual-channel capability allows for intelligent and seamless switching between beacons. The L-band satellite differential correction receiver requires a subscription to a differential correction service and provides multiple vendor support. The receiver ensures the satellite corrections to be uniformly accurate over the entire satellite coverage area without the degradation in accuracy associated with increasing distance from fixed reference stations.

Current Meter

Type 1 spin paddle type velocity apparatus is a kind of rivers hydrological instrument, mainly used for testing generally rivers, channels and reservoirs, lakes and section water in the average speed of flow measuring reservation, so as to determine the cross-section of the flow.

The key technical indexes/ 1. Speed range: V = 0.06 ~ 7.0 m/s/ 2. Work water depth: general is not more than 24 m;/ 3. Work water temperature: 0 ~ 40C;/ 4. Work water quality: fresh water (contain not excessive minerals) or contains the sediment muddy water/ 5. Continuous work of total time: 8 h;/ 6. Instrument up turn speed: V0 than 0.05 m/s/ 7. Check formula of the mean square error: 1.5% or m/ 8.

WL Gauge

Gauge for vapor pressure bomb testers with 1/4 in. NPT connection meets ASTM D323 and has an accuracy of 1/2 to 1% of the dial range.
