CompostWatch Temperature Monitoring System Overview

EcoProbe Wireless Temperature Probes

Our unique temperature probe design sets Reotemp apart from the competition. Each wireless temperature probe (EcoProbe) provides two temperature readings. One at the tip and a second roughly halfway up the stem. Our unique corrosion resistant design with a double walled stem and triple sealed enclosure provides unmatched protection from corrosion in the harsh compost environment. That’s why we back our EcoProbes with an industry leading 3 year warranty!

3 Year Limited Warranty

We’re confident our probes are the longest lasting, most durable wireless probes on the market. That’s why we back our probes with a 3 year limited warranty.

Corrosion Proof Stem

Our design prevents corrosion, while maintaining proper heat transfer. Our stem is made to withstand even the most corrosive biosolids.

Triple Seal Enclosure

Our proprietary enclosure keeps moisture and corrosive atmospheric gases away from electronic components, for a long lasting probe at outdoor, indoor and tunnel facilities.

Reotemp Wireless Technology

Our long-range custom wireless technology was developed from applications in locomotives, cranes, construction vehicles, and military vehicles. This makes our system far more reliable than “off the shelf” systems some competitive probe manufacturers use.

2 Year Battery Life

Our long battery life results in a probe that is reliable and low maintenance.

Roll Cage

Our stainless steel roll cage helps protect the enclosure from the bumps and bruises that come with the real world wear and tear at an industrial compost facility. It’s one of many design features that result in the most durable wireless probe on the market.

Dual Temperature Sensors

Dual sensors provide a temperature profile inside the pile, with a sensor at the tip and a second sensor halfway up the stem.


Made in the USA. Reotemp EcoProbes are manufactured in the USA under strict ISO 9001 quality guidelines.

60” Orange Locator Flag

Our locator flags prevent mishaps from losing sight of the probes in the compost pile.

PC vs PLC Systems

Depending on your needs we’ll help you choose either a PC or PLC system tailored to your site.

EcoProbe™ Reciever/Antenna

Reotemp’s EcoProbe™ System is customized to meet your facilities unique needs. Reotemp’s proprietary wireless system can be customized to increase transmitting power for even the largest of facilities.

ECOPROBE-wireless-antenna-compostEach facility has its own unique layout and setup, which means we’ll need to customize the antenna we use to fit your needs. On any application, we use only high quality antennas that are above and beyond what is needed. This ensures you’ll have consistent readings. It also accounts for the occasional interference typically found on composting sites (large equipment driving between probes and the receiver antenna, probes at various angles, etc.).

Reotemp’s receiver organizes data packets from EcoProbes located in the field. Typically, the receiver is mounted to an internal wall of the control building. The receiver is either hardwired into the PLC or wirelessly transmits its data to a personal computer. Depending on your facility needs you choose either a PLC or PC system option.

CompostWatch™ PC Software

For PLC systems, Reotemp partners with a 3rd party to create and customize HMI software to your facility. For PC systems, Reotemp offers  windows-based software called CompostWatch PC.

CompostWatch PC software displays live temperature readings as they come in from the radio link. It also displays a log history of the readings and the history can be viewed graphically or exported into standard Windows applications such as Excel. Unlimited phone support is offered for the CompostWatch  PC software. We stand behind our products.

Other features include:

  • Data range selector with quickset or custom date ranges
  • Low & High temperature alarms & warnings
  • Online/Offline indicator light
  • Battery status indicator light
  • Temperature Chart
  • Temperature Table
  • Remote access from network computers or via the internet available.
