Automated cleaning

Washes each instrument automatically, on a schedule you set, to maintain data quality and reduce ongoing maintenance.

Wildlife deterrence

Detects wildlife and uses non-harmful deterrent movement to keep it away from the instruments.

Mains-fed water supply

Runs on your mains water supply, with particle and de-ionising filters and an optional irrigation-grade booster pump where existing mains water pressure is low.

FAQs

What site preparation is required?+

You’ll need mains power (230 Vac), a water supply (400–600 kPa) and, optionally, communications cabling. MetLite also needs a suitable mounting base, such as a roof structure or concrete work area.

How long does installation take?+

MetLite is delivered partly assembled on its mounting pole, ready to deploy in 1–2 hours from placement, excluding site power and water connections.

Can I install it myself?+

Yes. MetLite is suited to self-installation.

Are there special requirements for the water?+

No. Built-in filtration produces high-purity water for instrument cleaning and removes potentially damaging minerals where water is hard.
