Sensors for the Agricultural Industry

Why pH? The pH of the water-nutrient mixture is of prime importance to efficient dosing systems in hydroponics. All the nutrients the plants need for growth may be present, but if the pH of the solution is too alkaline or too acidic the plants will not be able to absorb the nutrients that have been provided. Correct pH levels are important for the plants to be able to utilize all the nutrients supplied in the solution. Agriculture/Hydroponics Brochure.pdf

Low Pressure Handheld pH Sensor This pH sensor is used for low-pressure in-line measurements and handheld measurements. Useful for almost any low-pressure application, it can be used to manually measure samples and even used with a compression fitting to measure samples in-line. The rugged polymer body of this sensor is thicker than most other polymer models and provides extra protection against accidental impact. In addition, this pH sensor is rugged enough to be used in a media-based environment Part Number: C2451C-12A-A10BC Specifications: pH Range 0-12 pH Temperature Range: 0-80°C Glass Membrane Type: GP, Low Sodium Ion error Membrane Resistance: 100 Megohms Reference System: Ag/AgCl
	C2451C-12A-A10BC Specifications

High Pressure In-Line with Integral Housing This pH sensor has its own integral housing so that it can be installed into any 1/2" NPT pipe fitting. No separate housing is needed because the electrode and the threaded housing are built into one unit. pH sensor is threaded to fit directly into the pipe Standard 1/2" Tee joint Part Number: C1121K-32A-A10BC pH Range: 0-13 pH Temperature Range: -5-100°C Glass Membrane Type: HT-3, Low Sodium Ion error Membrane Resistance: 100 Megohms Reference System: Ag/AgCl Pressure Rating <150 psig (10 bar) @ 25°C
	C1121K-32A-A10BC Specifications

High Pressure In-Line pH Sensor This pH sensor is designed to fit into the built-in housings of the dosing units on the most widely used automated liquid fertilization systems in the hydroponics industry. pH sensor easily fits into both the conventional threaded housing and the new twist-lock housing. Part Number: C1101A-32A-A10BC pH Range: 0-13 pH Temperature Range: -5-100°C Glass Membrane Type: HT-3, Low Sodium Ion error Membrane Resistance: 100 Megohms Reference System: Ag/AgCl Pressure Rating: <150 psig (10 bar) @ 25°C

Tips & Hints One of the most common problems that growers encounter with pH sensors in agricultural applications is corrosion of the connectors due to moisture. If the connectors get wet, the output of the sensor will be shorted making calibration of the pH sensor impossible. To prevent the sensor from malfunctioning, it is very important to keep the connectors dry in a water-culture system.	Note: All sensors come standard with a 10 foot (3 meter) low noise coaxial cable and either a BNC Plug or a crimped Ferrule connector. To order a sensor with the fully ferruled connector, simply change BC to FF at the end of any sensor part number.
