Manufacturer: Thermo Scientific Brand: Oakton Model: WD-35661-11

The Oakton 35661-11 TDS Testr Low is a handheld, waterproof and dustproof pocket meter that measures Total Dissolved Solids (TDS), floats, if dropped in liquid, and has + or - 1% full scale accuracy. A portable pocket meter is commonly used to measure the TDS of substance in aquaculture, aquariums, fish ponds, food processing, swimming pools, and in environmental treatment. This microprocessor meter features a TDS range of 0 to 1990 ppm (10 ppm resolution) to measure TDS in natural water, verify reverse osmosis system operation and tap water quality, and to check nutrient solution concentration in hydroponic applications. It has one-point, push-button calibration located in the battery compartment to avoid accidental recalibration, and has Automatic Temperature Compensation (ATC) for accurate readings in fluctuating temperatures. It has a replaceable sensor to extend the life of the tester. The meter’s waterproof and dustproof housing is Valox resin, and has an IP67-rating for protection against solid objects or liquids. Its stainless steel sensor tip is both durable and chemical resistant. The meter displays full readings to obtain actual test values, and eliminates the need to multiply the readout. It has a hold function which freezes readings for recording, and an auto shut-off that automatically turns the tester off after 8.5 minutes of nonuse to extend battery life. It has a transparent, protective cap to reduce contamination and protect the sensor. The cap keeps the sensor moist when stored upright, and can be used as a container for sensor-conditioning, or on-site calibration. A lanyard loop located on the top of the battery cap secures attachment. The 35661-11 TDSTestr Low pocket meter comes with an integral stainless steel sensor, has ATC from 0 to 50 degrees C (32 to 122 degrees F), and an operating temperature of 0 to 50 degrees C (32 to 122 degrees F). Calibration standard range is 300 to 1990 ppm, with ATC coefficient Beta=2% per degrees C, 1.11% per degrees F, 25 degrees C reference temperatu...

Manufacturer: Sper Scientific Brand: Sper Scientific Model: 850038P

Sper Scientific 850038P Conductivity Probe for use with the following meters: 850038 Pure Water Meter, 860032 Benchtop Conductivity/TDS/Salinity Meter, 860033 Benchtop Water Quality Meter.

Manufacturer: Cole-Parmer Brand: Oakton Model: AO-35662-35

Use these testers for either Cup-Style or dip-style measurements. For cup style, pour a small amount of your sample directly into the sensor cup until it overflows; for dip style, simply immerse Tester tip into sample. Replaceable sensor lets you reuse meter body many times over. Valox housing and stainless steel electrodes for good chemical compatibility. Note: before measuring, calibrate Tester as either cup style or dip style (depending on intended method of use). what's included: protective plastic storage case, lanyard, and batteries operate as either a Cup-Style or dip-style Tester for greater flexibility automatically or manually Select measuring range waterproof, Dustproof housings Float push-button calibration, hold function, and error messages

2 Spectra Mod 860 Potentiometers (L27-4)

Manufacturer: Thermo Scientific Brand: Oakton Model: WD-35608-50

The Oakton 35608-50 is a conductivity/Total Dissolved Solid (TDS) electrode, with cell constant of K=1.0 for mid-range conductivity measurements. The electrode, also known as a probe, measures the conductivity and TDS of a solution, and is commonly used in testing water, such as pure and sea water, in field and laboratory applications. This probe features stainless steel sensors for specific application, Polyetherimide (PEI) ultem-body housing for chemical resistance, and an 8-pin DIN connection for stability. It comes with a removable, plastic probe guard to preserve the unit. The 35608-50 electrode has a temperature range of 0 to 80 degrees C (32 to 176 degrees F) and is used for mid-range conductivity measurements. Its dimensions are 100 (l) x 12 (d) mm. It is intended for use with the Oakton CON 400, and meters that have 5-pin Deutsches Institut für Normung (DIN)-connections (sold separately). It comes with a 3-foot cable. An electrode is used with a meter to measure the parameters of a substance. Conductivity is the ability of a solution or material to conduct an electrical current. TDS measurement indicates materials such as salts, bases or minerals, which contribute to electrical conductivity, within a solution. Oakton Instruments manufactures an array of scientific instruments for research, industrial, and educational uses. Since 1991, Oakton has distributed a wide variety of instruments such as meters, electrodes, and transmitters. Oakton is based in Vernon Hills, IL, and has facilities in Europe, Asia, and China.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: BL983324-0

BL 983324 is a panel mounted TDS controller, designed for easy installation, configuration and maintenance. The meter is provided with a dosing relay, activated when the TDS reading exceeds the set point value. Measurements are compensated for temperature variations and shown on the display automatically. A multicolored LED on the front panel continuously indicates if the mini controller is in measurement, dosing or alarm mode. Wiring and external device connections are extremely simple to perform through the terminals on the rear of the instrument. Users can choose automatic or manual dosing mode with a switch on the front panel. Manual control is particularly useful during maintenance operations, because it permits operators to enable or disable the dosing relay according to need. The overtime control system advises operators when the relay is active too long, helping to prevent over dosage. This model is supplied with mounting brackets, transparent cover and instruction manual. Range: 0.0 to 49.9 ppm. Resolution: 0.1 ppm. Accuracy at 25 degree C +/-2 percent F.S. 0.5 TDS Conversion factor. Temperature compensation: automatic, 5 to 50 degree C (41 to 122 degree F) with ß = 2 percent/ degree C. Calibration: manual, with CAL trimmer. Dosing relay: maximum 2A (fuse protected), 250Vac, 30 VDC contact close when measure > set point. Setpoint: adjustable from 0 to 49.9 ppm. Overtime: adjustable, typically from 5 to approx. 30 minutes. Measures 3-3/32" length by 1-57/64" width by 3-11/16" height.
