Farmtrenz is a division of Electronic Specialists that designs and manufactures electronic farm monitoring systems. Our key effluent control products give farmers peace of mind their effluent is going to land and not to waterways. We also make a range of other farm-related products.

TIM™ stands for Travelling Irrigator Monitor.

Our marquee fail-safe product monitors pressure and speed in the paddock, stopping the effluent pump when the irrigator reaches the end-of-travel and if the cable breaks. 

TIM™ mounts to all travelling effluent irrigators including Cobra, Torpedo, Weta, Briggs, Plucks, Williams, Ecostream, Numedic, Irri-Max, Spitfire.

KIM™ stands for K-line Irrigator Monitor.

A fail-safe effluent device for low application rate pods or mini rainguns, KIM™ monitors effluent pipeline pressure in the paddock – not back at the pump – and stops the pump when a blockage or leakage is detected.

Single or multi KIM options for pulsing between sets of pods at different areas of a farm, helping you move more effluent quicker. Also works with indexing valves. 

PIM stands for pivot irrigator monitor. Designed for large farms using centre pivot water irrigators with underslung effluent lines, PIM monitors effluent pressure through droppers or rainguns. Mounts to wheel frame.

Hub, as its name implies, is the central brain or controller for all Farmtrenz monitoring systems.

Wall-mounted in the cowshed or central office, the Hub receives signals from all connected field devices and monitors their performance.

Hub can also connect to a computer where performance data can be logged and viewed via optional Farmtrenz software.

PondLink is the pond to shed remote link to the Hub that controls all connected pumps used for effluent irrigation, transfer and agitation.

Located at the contactor cabinet in the pump shed, it protects pumps from over-pressure and running dry, including loss of prime. It will also control electric actuator valves.

The D-PondLink model displays status information.

Measures the level of water in a tank or tanks.

It can also measure water flow rate from bore to tank or trough when connected to a magnetic or mechanical/paddle flow meter.

Ideal for water permits requiring usage monitoring when combined with GUI software.

Controls and monitors the filling of remote hilltop water tanks.

Automatically turns on the pump when the tank level is low and turns it off when the level reaches the high setpoint.

No more worrying if stock run out of water!

Measures soil moisture, soil temperature, rainfall, air temperature, wind direction, wind speed and humidity.

Includes solar panel for charging the battery.

See how the weather's impacting your farm with Farmtrenz GUI software for graphical display and analysis.

Measures volts on a remote electric fence line. Adjustable low V setpoint. Know when there’s a fence outage and avoid a potential stock break-out.

In development. Low cost pulse unit ideal for monitoring portable break fences controlling grazing stock

Vat Monitor monitors milk temperature and multiple cooler, vat wash and tap sensors. Meets new MPI milk regulations: data is logged and viewable historically and in real-time on Farmtrenz software. Receive text alerts through optional Text Unit if something goes wrong.

Text Unit sends text alerts to your cellphone relayed from our Hub controller when it senses something wrong with the operation of your effluent, vat or water systems equipped with Farmtrenz monitoring field devices.

Know what's happening on your farm when it happens!

Smart Text is a text alert unit for water tanks, effluent tanks and milk vats.

You can send a text from you cellphone and it will text back with level or temperature readings – instantly! 

Ideal for remote hilltop tanks when you want to know its water level or when you want to check if your milk refrigeration plant is working correctly.

The Farmtrenz Text Unit connects to a number of monitoring devices in the field.

Add a GPS transmitter to your TIM-, KIM- or PIM-equipped effluent irrigator to track runs for application mapping using your digital farm map.

See and record what’s happening on your farm from connected Farmtrenz field devices historically and in real-time through our graphical software on a Windows computer. It will also log the data for council or dairy company compliance purposes.

A House Receiver receives signals from various Farmtrenz field devices on your farm and records and stores data on your home computer via our GUI software.

A Repeater boosts signal range when a hill, forest block or other large physical barrier blocks signals relayed back to the Hub from Farmtrenz field devices.

We service what we sell.

It could be as simple as replacing an aerial chewed by a cow, or something more serious.

We continuously innovate to make our products better, so if you're finding your early model device is playing up we have cost-effective upgrades available.

We have a network of authorised installers in most regions of NZ.

We always have an inventory of parts on hand. Call us for ordering parts direct.

We started out more than 30 years ago repairing a wide range of electronic farm devices.

These include fence energisers, livestock weigh scales (consoles and load bars), pasture platemeters, calf milk warmers and portable shear pieces.
