Milwaukee Tds Meter

Mi150 is an advanced pH/Temp microprocessor-based bench meter. It is ideal for students and technicians who need fast and reliable measurements.
This meter is provided with a series of new diagnostic features which add an entirely new dimension to the measurement of pH, by allowing the user to dramatically improve the reliability of the measurement:
Automatic Temperature Compensation (ATC) for good accuracy under fluctuating temperatures
Easy to read large custom LCD
Easy and Quick Push-button Calibration
7 memorized buffers (pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45) for calibration
Messages on the LCD to make the calibration easy and accurate
User-selectable “calibration time out” to remind when a new calibration is necessary
Stability Indicator prompts whenever reading stabilizes.
Moreover, it offers an extended temperature range from –20°C (–4°F) to 120°C (248°F),using the MA831R interchangeable temperature probe.

Mi180 pH / ORP / Conductivity / TDS / NaCl / Temperature Laboratory Bench Meter
Mi180 measures 6 different parameters: pH, ORP, EC, TDS (Total Dissolved Solids), percentage of NaCl and temperature in a variety of ranges.
pH calibration can be performed in 3 points selectable between 7 memorized buffers, to provide a very accurate calibration curve even when testing different samples, where very wide differences in pH can be found.
The auto-ranging feature for EC and TDS measurements automatically sets the resolution suitable to the tested sample.
All measurements can be temperature compensated at 20 or 25°C and the compensation coefficient is selectable by the user.
The automatic temperature compensation can also be disabled for measuring the actual conductivity value. The stability indicator on the LCD ensures accuracy. Conductivity readings are performed with the 4-ring probe supplied with the meter.
The GLP feature allows users to store and recall data on system status. PC compatible through an RS232 port or USB.

Mi190 Dissolved Oxygen / Temperature Laboratory Bench Meter
Ideal for testing Dissolved Oxygen in the pharmaceutical and food Industry, as well as monitoring in water treatment plants. The user can choose to measure D.O. readings in mg/L or % of saturation of O2.
This meter can be used for any type of water, as it allows measurements to compensate for temperature, altitude and salinity factors. The automatic logging interval can be set to perform analysis and store data into the memory.
All logged data can be downloaded to your PC through an RS232 or USB serial port. Memory can store up to 50 samples.
Mi190 features an automatic calibration procedure, at 1 or 2 points (at 0 and 100% of O2 saturation). The polarographic probe supplied with the meter (MA840/2) measures the current generated by the reaction of O2 with Ag.
Mi190 is supplied complete with MA840/2 DO probe with 2 m cable, 2 spare membranes, MA7041 electrolyte solution (30 mL), 12 VDC power adapter, probe holder and instruction manual.
