The Hanna Instruments BL983321-0 TDS Mini Controller is a highly efficient process controller designed to monitor the total dissolved solids (TDS) of a process stream within the range of 0.00 to 19.99 ppm (mg/L). The device comes with a large LCD screen and protective cover, making it easy to read and use. This mini controller features an automatic or manual dosing mode, allowing users to choose the most convenient option for their process.
Additionally, the BL983321 has a dry contact relay that is activated when a reading is above the set point. The relay can be used to activate a solenoid that switches from one DI (deionized) tank to another or to open a valve that allows lower TDS water to flow into a tank being monitored in order to lower its TDS. This mini controller is also ideal for monitoring the quality of water produced from ion exchange, reverse osmosis (RO), or distillation.
The BL983321 uses a 0.5 conversion factor, where 1.00 S/cm equals 0.50 ppm. The device also features a multicolor LED indicator and a fire retardant casing for added safety. It comes with mounting brackets, transparent cover, and an instruction manual for easy installation and use.
In terms of technical specifications, the BL983321 has a TDS resolution of 0.01 mg/L (ppm) and TDS accuracy of ±2% F.S. at 25°C/77°F. The temperature compensation is automatic from 5 to 50°C (41 to 122°F) with an accuracy of ±2%/°C. The mini controller is calibrated manually, with a CAL trimmer, and has a dosing relay of maximum 2A (fuse-protected), 250 Vac, 30 VDC contact close when measuring above the setpoint. The overtime is adjustable, typically from 5 to approximately 30 minutes. The BL983321 is available in two models, one with a 12 VDC adapter (included) and the other with a 115/230 VAC; 50/60Hz power supply.
To use this mini controller, it is recommended to pair it with the HI7634-00 EC/TDS probe, which features an internal temperature sensor and a 2 m (6.6 ft) cable (not included). The BL983321 has dimensions of 83 x 53 x 99 mm (3.3 x 2.1 x 3.9 in) and weighs 200 g (7.1 oz.) for model -0 and 300 g (10.6 oz.) for model -1.
Overall, the Hanna Instruments BL983321-0 TDS Mini Controller is an excellent choice for businesses and laboratories that require precise and reliable TDS monitoring in their processes.
