Pacific Sentry LLC products

Designed to detect ammonia levels ranging from 1ppm (30 times below the point at which ammonia can be smelled) to 5+ ppm, this sensor will consistently provide the protection needed to ensure a safe, ammonia-free environment.  It is constructed with a state-of-the-art, colored membrane, which changes from a canary-yellow to a deep-blue color in the presence of ammonia. Because the ammonia diffuses into and through the membrane, it does not physically change the membrane, allowing the sensor to be used repeatedly. Note - reversion to its baseline color (canary-yellow) can take an unspecified amount of time depending on conditions (e.g. variables such as the concentration and duration of ammonia exposure, air circulation, temperature).

Pacific Sentry`s ammonia aqua sensor enables visual monitoring of toxic ammonia (NH3) in aquaria water on a continuous basis. Simply attach it in a visible location where it can be left and easily viewed, with the sensor pad completely immersed. With initial use, wait about 15 minutes for the sensor to hydrate before making first reading. Thereafter they respond quickly (1-5 minutes) to NH3. To get a measurement, simply match the sensor`s color to the color-gradient indicator chart to readout the NH3 concentration.

Designed to detect ammonia levels ranging from 0.1 ppm to 0.25+ ppm in refrigerant solutions, these strips enable identification of NH3 contamination within secondary fluid loops. Using strips consistently in routine monitoring programs will provide additional protection needed to ensure a safe, efficient, ammonia-based cooling system. Conducting this simple dip-stick test of secondary fluid samples shows visually if there is ammonia leakage from the primary-coolant side of the system.

When the pH sensor becomes exhausted, a new sensor can easily be replaced for the old one through the convenient insertion slot. * included with each Ammonia/pH Aqua sensor are 2 additional pH sensors

This specially designed PTFE tape conveniently and economically detects ammonia (NH3) leaks. The tape has visual indicators that change color identifying leaks or defects in pipe systems, joints and couplings that contain ammonia. The tape, similar to the use of standard “plumbers tape”, is simply wrapped around the pipe or fitting and is inspected/monitored over time.

Pacific Sentry’s CAFO Ammonia Sensor conveniently provides a 3-hour time-weighted average of ammonia levels on a continuous basis. The visual sensor changes color (from golden yellow to blue) depending on the ammonia concentration in the surrounding environment. With a quick glance of the sensor, average ammonia levels can be easily determined. Whether you operate as a large-scale poultry broiler or small family-owned farm, this sensor will give you the ability to monitor your ammonia levels on a continuous basis. No longer rely on infrequent sampling with passive dosimeter tubes, gas detection tubes, electronic ammonia meters or the infamous “smell test”. The CAFO Ammonia Sensor will provide the information you need to easily determine if your poultry house, cattle farm or swine operation is functioning optimally and ammonia levels are being maintained to a minimum.

The Ammonia/pH sensor enables visual monitoring of toxic ammonia (NH3) and pH levels in aquaria water on a continuous basis. Simply attach it in a visible location with both sensor pads completely immersed. With initial use, wait 15 minutes for the NH3 sensor to hydrate and up to 24 hours for the pH sensor to hydrate before making first reading. Thereafter they respond quickly (1-5 minutes) to changes in NH3 and pH.
