AI3108 LabSen 801 Glass-body pH Electrode for Purified Water& Low Ion-Concentration Solutions by Apera

Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 801 Glass-body pH Electrode is made for pH measurements of pure water such as distilled and deionized water, and other low ion concentration solutions.

LabSen L-type glass membrane - fast response in low ionic strength solutions thanks to its ultra-low resistance formula (>50M&Omega), providing fully stabilized readings in 30 to 60 seconds.

Movable Sleeve Junction - easy to clean, especially suitable for low ionic strength solutions, emulsions, and suspensions. The infiltration rate of the electrolyte can be adjusted by the tightness of the sleeve.

Silver Ion Trap Reference System - On top of the Long-Life reference system, a silver ion trap is added to further prevent junction clog.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera Instruments MP500) to enable ATC or manually input temperature to realize temperature compensation.

• Proprietary sensor technology and premium materials from Switzerland
• Built with LabSen L-type glass membrane for low ionic strength solutions
• Movable Sleeve Junction - easy to clean, adjustable infiltration rate
• No more air bubbles inside the glass membrane thanks to the Swiss blue gel electrolyte.
• Silver ion trap reference system

EM803-PH 4-20mA & Modbus 485 pH Electronic Module by Sensorex

The EM803-pH is our most cost-effective solution for connecting our S8000 series pH sensors to a PLC or SCADA system. This small electronic module functions as a blind pH transmitter with 4-20mA or optional MODBUS/RS485 output. No additional instrumentation is required to condition the sensor signal to be read by your PLC or SCADA. It can also be used to pair Sensorex sensors with any controller that has a 4-20mA or RS485 input card. Easily connects to our S8300 Modular pH Sensor Package to form a complete pH monitoring solution.

• Blind 4-20mA or MODBUS/RS485 transmitter for connecting pH sensors to PLC or SCADA
• Small form factor saves valuable panel space
• Input Voltage Options: 12V DC – MODBUS only; 24V DC – 4-20mA & MODBUS
• Compatible with S8000 series inline and submersion pH sensors
• Compatible with PT1000 RTD temperature compensation

AgrowDose™ AD1 Peristaltic Dosing Pump by Agrowtek

AgrowDose AD1 dosing pump is a rugged and economical singlehead peristaltic pump designed for injecting nutrient solutions, pH buffers and more into stock tanks or pressurized water lines up to 20psi.

AD1 Pump operates at a fixed speed (~50mL/min) when powered and requires a controlled outlet to operate the pump (such as RX1 or RX4.) Includes a standard wall plug power supply.

Pump heads feature an intlet tube and an outlet tube. Simply place the inlet side into any size nutrient or buffer stock tank and route the outlet to the reservoir. Pumps can draw solutions up to 10ft vertical lift and do not require priming. Peristaltic action resists fouling or clogging even with thick fluids.

Features

• Single dosing pump
• Precision dosing accuracy: Fixed flow rate, non-reversable
• Easy-change pump heads: Twist & replace; no tools required
• Durable powder-coated steel enclosure
• Made in USA
• 1-Year Warranty

Typical Applications

• Agricultural Nutrient or pH Dosing
• Industrial Chemical Dispensing
• Laboratory Dispensing
• Aquarium
• Pool & Spa
• OEM & Custom Applications
