Manufacturer: Nutradip (Tri Meter) Brand: Nutradip

The Nutradip Nutrient (TDS) meter will continuously measure the concentration of the Total Dissolved Solids (TDS) or nutrient levels in the growing solution being provided to the plants. It will assist in ensuring optimum growth in your hydroponic operation. The critical TDS measurement of your nutrient solution can be presented as parts per million (TDS meter) or as the electrical conductivity (EC meter) of the nutrient solution.

BL 983317 is a panel mounted mini controller with an output relay that has been designed for easy, affordable installation in tight spaces, ideal for simple yet effective process control. This instrument is provided with automatic compensation for variations in temperature. The calibration is performed at one point, through a trimmer. All wiring and connections to external devices are done through the terminals on the rear panel. The multicolor LED continuously indicates if the controller is in measurement, dosing or alarm mode. Manual control is particularly useful during maintenance operations because it permits operators to enable or disable the dosing relay according to need. To help prevent overdosing, the overtime control system advises users when the relay is active too long. This model is supplied with mounting brackets, transparent cover and instruction manual. Range: 0.00 to 10.00 millisecond per centimeter. Resolution: 0.01 millisecond per centimeter. Accuracy at 25 degree C: +/-2 percent F.S. Calibration: manual with CAL trimmer. Temperature compensation: automatic, 5 to 50 degree C (41 - 122 degree F) with Beta =2 percent/degree C. 115/230V Power supply. Dosing relay: maximum 2A (fuse protected), 250VAC, 30 Vdc. Setpoint: adjustable from 0 to 10 mS/cm. Overtime: adjustable, typically from 5 to approx. 30 minutes. Measures 3-3/32" length by 1-57/64" width by 3-11/16" height.

Dissolved Oxygen Test Kit Atlas-scientific Dissolved Oxygen Stamp is a highly compact D.O. monitoring system that fits into any breadboard. This design configuration allows the user to accurately monitor D.O. without having to add any additional circuitry or components to your design. Communication with the D.O.Stamp is done using only eight simple commands. The D.O.-Stamp provides scientific grade readings to any embedded system that has an RS232 connection interface. Features: Dissolved Oxygen Kit comes with necessary components to quickly take accurate readings of dissolved oxygen using your existing micro-controller such as an Arduino or Raspberry Pi. The Dissolved Oxygen circuit returns data in Mg/L up to two significant figures. Readings can be taken either dependent or independently of temperature or conductivity. Dissolved Oxygen Circuit can take readings from any galvanic dissolved oxygen sensor. Dissolved Oxygen Kit, just add the microcontroller of your choice to start taking accurate dissolved oxygen measurements. Data format is ASCII.

Product Description: A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-3 can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS-3 is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS-3 is a great tool for drinking water, water filtration and purification, colloidal silver, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, commercial and industrial applications and more. The TDS-3 is a rugged model that includes a protective carrying case. This is the world's most popular handheld TDS meter for industry professionals.
