Pressure Instruments


Temperature is crucial for agricultural production and animal welfare.
Temperature instruments are placed inside livestock houses to measure and monitor the temperature, ensuring animals remain comfortable and don’t overheat or freeze. Real-time temperature monitoring allows for timely ventilation adjustments, ensuring an optimal climate with minimal energy costs to ensure the optimal climate and prevent wide temperature swings that can lead to higher mortality rates.
When selecting temperature sensors for livestock houses, it is essential to choose Tel-Tru sensors that provide accurate measurements and have a long lifespan. Our high-quality sensors withstand the harsh conditions of farm buildings, including high humidity, and high levels of dust, ammonia, and CO2. These sensors are reliable and maintain accuracy even after years of exposure to the challenging environment.
Tel-Tru thermometers, RTDs, and Remo-Tel SMART temperature monitoring systems are engineered to endure the tough conditions typically found in livestock environments. These instruments provide precise temperature data, enabling farmers to make immediate adjustments to maintain a stable environment

Real-Time Data Alerts
The Remo-Tel remote temperature monitoring system helps agriculture managers, farmers, and ranchers detect issues instantly through real-time data alerts on their mobile devices. Insights from trending data help reduce costs, optimize maintenance, boost efficiency, increase crop yields, and keep livestock healthy.
Remote Alerts
If something goes wrong, sensors can alert you via text, email, or call, securing valuable assets and livestock by ensuring environmental temperatures are optimized. Temperature checks in enclosures like coops and barns are essential for livestock well-being. With many equipment types and animal care buildings on a farm or ranch, maintaining consistent temperature monitoring is crucial.
Customizable Alerts for Critical Parameters
Early warning signs of equipment failure or subpar growing conditions are often hard to detect, especially when numerous demands prevent constant monitoring. Customizable alerts for critical parameters ensure that you receive timely notifications for unusual conditions. How long does it take for you to learn about equipment failures, power outages, or other life-threatening issues? Swine, poultry, cattle, and other animals require optimal living conditions to stay healthy and maximize yields.
If a power failure or ventilation system malfunction occurs when staff is off-site, it could spell disaster for your livestock and business. Environmental changes can disrupt production and decrease revenue. Many facility owners and managers rely on manual walkthroughs to ensure a controlled environment, which is inefficient, time-consuming, and costly. Fortunately, there is a more efficient way to maintain a temperature-controlled environment.
Reduce Risk and Expense with Preventative Measures
Real-time updates and 24/7 monitoring allow you to stay ahead of potential threats, protecting your animals from rising/falling air temperatures, poor ventilation, power failures, and equipment malfunctions. If conditions fall outside preset parameters, the system acts as an auto-dialer, alerting you and your staff immediately via phone, email, or text. This reduces the time and money spent on monitoring your facility.
Detecting issues early is critical to preventing significant livestock loss. The faster you become aware of a threat, the quicker you can respond, potentially saving your animals. Whether you raise poultry, swine, cattle, or other livestock, continuous monitoring is essential to ensure environmental conditions such as temperature remain within safe ranges. Tel-Tru thermometers and monitoring systems help you monitor high and low-temperature conditions and equipment failures, sending multiple phone alerts to ensure problems are addressed promptly. Our systems also support data logging for operational history review, enhancing long-term management and efficiency.
