The Hanna Instruments BL981411-0 Mini pH Controller is a compact and highly efficient pH process controller designed for applications where space or cost is an important factor. With its high impedance pH input, it can be used with any pH electrode that has a standard BNC connector. The device comes with an adjustable dosing relay that can be configured to dose above or below a user-programmable pH setpoint. It also allows users to choose between automatic or manual dosing modes for easy maintenance and troubleshooting.
The BL981411 Mini pH Controller is housed in a fire retardant casing and features a large and clear LCD display. With a pH range of 0.0 to 14.0 and a resolution of 0.1 pH, this device is highly accurate, with a pH accuracy of ±0.2 pH at 25°C/77°F. The device's calibration is manual and can be done through CAL (offset) trimmer. The dosing relay has a maximum 2A (fuse protected) capacity and can work with 250 Vac or 30 VDC.
The BL981411 Mini pH Controller's dosing selection can be set to work with an acid or alkaline contact. The contact open mode is for acid dosage, and the relay is on if the measurement is above the setpoint. The contact closed mode is for alkaline dosage, and the relay is on if the measurement is below the setpoint. The setpoint is adjustable from 0 to 14 pH, and the overtime is adjustable, typically from 5 to approximately 30 minutes.
This device has a high input impedance of 10^12 Ohm and comes in two power supply options: 12 VDC adapter (included) or 115/230 VAC, 50/60Hz. The BL981411-0 weighs 200g (7.1 oz.), while the BL981411-1 weighs 300g (10.6 oz.). The device comes with mounting brackets, transparent cover, and instruction manual, while the HI1001 PVDF body pH electrode with 1/2" NPT thread, BNC connector, and 3m (9.8') cable for continuous flow-thru monitoring is recommended for optimal performance (not included).
In conclusion, the BL981411 Mini pH Controller is an excellent device for applications that require a compact and cost-effective solution for pH process control. Users can direct the device to dose above or below the setpoint, depending on their needs, and switch back and forth between automated and manual dosing modes. With its highly accurate measurement, clear display, and easy-to-use interface, this device is the perfect solution for maintaining optimal pH conditions.
