THORNTON 770MAX Multiparameter Analyzer/Transmitters with Smart Sensor Technology allow monitoring 6 channels of conductivity, resistivity, pH, ORP, dissolved oxygen, ozone, TOC, flow, temperature, pressure, and level.
Smart Sensors automatically identify themselves to the 770MAX transmitter, providing set up and unique calibration data for instant multiparameter configuration.
The M300 transmitter for pH/ORP measurements combines robustness with ease of use. It includes on-line sensor diagnostics, auto buffer recognition and internal PID control. The M300 transmitter is designed for ease of operation: from the large display to the easily accessible wiring terminals to the plain text interface and quick setup menu. It is available with either 1/4 DIN panel mount or 1/2 DIN wall mount case.
With its innovative USB port, the M300 is open to the future – for remote configuration, data logging or software upgrade.
Other M300 models include measurements of conductivity/resistivity, dissolved oxygen, and dissolved ozone.
Thornton’s 550 Total Organic Carbon Analyzer provides continuous online TOC analysis of pure and ultrapure waters, using proven UV-Oxidation/Differential Conductivity measurement technology, simultaneously displaying sample water TOC, resistivity or conductivity (un-compensated or compensated) and temperature. The 550TOC analyzer meets pharmaceutical <643>, <645> and EP 2.2.44 as well as semiconductor ultrapure water monitoring requirements.
The 5000TOC Sensor uses Smart Sensor technology to interface with the 770MAX Multiparameter Analyzer Transmitter which can measure numerous other water treatment parameters as well.
The TOC sensor uses proven ultraviolet (UV) oxidation with differential conductivity to effectively determine TOC concentrations.
The 5000TOC meets pharmaceutical <643>, <645> and EP 2.2.44 as well as semiconductor ultrapure water monitoring requirements.
METTLER TOLEDO “premium line” 2- and 4-electrode sensors for industrial conductivity measurement applications, provide you with the highest degree of safety during CIP and SIP processes. These sensors are specially designed and ruggedly built to withstand most rigorous cleaning procedures.
These robust sensors are also highly suitable for applications in the chemical industry and in the treatment of industrial wastewater.
The new InPro7250 Series of inductive conductivity sensors from METTLER TOLEDO is designed for in-line measurements of conductivity/concentration levels of acids, bases and salts in liquid media. Main fields of application are in the chemical industry (CPI), pulp and paper processes, as well as monitoring industrial effluents. The design is based on an electrodeless toroidal principle (electrodeless).
The sensors of the InPro7250 Series are fully compatible with METTLER TOLEDO’s “Advanced and Premium Line” transmitters offering 4-wire, 2-wire, HART®, FOUNDATION Fieldbus and Profibus® PA instruments.
These 2-electrode sensors from METTLER TOLEDO with integrated Pt1000 are accurate and easy to install in pipe lines or tanks. They reliably meet the demands placed on measurement technology today in basic applications in the chemical and food & beverage industry, ranging from ultra pure water through to industrial wastewater.
The sensor provide both improved price/performance ratio and enhanced versatility in process connections.
METTLER TOLEDO Thornton offers a wide variety of both analog and digital conductivity/resistivity sensors to accommodate pure water applications.
UniCond™ with Intelligent Sensor Management (ISM) provides an exceptionally wide measurement range, highest accuracy, and diagnostics. This next generation conductivity system features Plug and Measure compatibility for easy installation and real-time process control.
THORNTON provides a full complement of analog conductivity sensors with NPT or TriClamp® sanitary fittings. They include various lengths, cell constants and materials to fit different applications.
METTLER TOLEDO’s pH/Redox electrodes with liquid electrolyte allow refilling of the electrolyte reservoir, and are especially suitable for applications where precise measurement values are important. With correct maintenance, they are very well known for their long service life, even under harsh operating conditions.
These electrodes are used with appropriately designed housings allowing the reference electrolyte to be kept at a slight overpressure. All models are available with temperature-compensation.
METTLER TOLEDO pH/Redox electrodes with gel- or liquid-type electrolyte or solid polymer (XEROLYT®) reference system, all with open junction, obviate the need to pressurize the electrode through the housing. The gel electrode is pre-pressurized and the polymer reference system is (process) pressure-resistant. These types of electrode cannot be refilled and therefore require reduced maintenance.
They are widely used for routine measurements, particularly in applications involving media with a high fouling potential. Many models enable temperature-compensated measurements and enhanced sensor diagnostics.
Some pH-electrodes with integrated ISM functionality (Intelligent Sensor Management) allow “Plug and Measure” and advanced diagnostics.
pH electrodes with polymer body and designed for direct mounting into a vessel or pipe. Temperature compensation of the measurements (RTD) is standard. The currently available electrode series has a solid polymer (XEROLYT®PLUS) reference system and an open junction.
Recently developed, unbreakable solid-state ISFET pH electrode specially intended for use in the food processing industry, where the possibility and consequences of fractured glass present a highly dangerous threat. It complies with 3-A sanitary standards, has been tested to EHEDG requirements and is in compliance with FDA regulations.
A wide variety of METTLER TOLEDO pH electrodes with VP connection can meet diverse application requirements. Smooth membrane surfaces and unique reference junction designs resist fouling in dirty samples. The pHure Sensor uses a shielded flow chamber and a continuous outflow of reference electrolyte for stable measurement in low conductivity samples. pH electrodes with Intelligent Sensor Management® maintain calibration and other data in internal memory, enabling pre-calibration in the lab. Their digital output signals are far more robust for transmission back to the instrument.
