The Model 4150 Conductivity/TDS Meter is designed and constructed to resist the harshest of field, laboratory and industrial environments. The whole system is waterproof to IP67, and if dropped into water will float. These products are ideal for on-site water quality measurement in a multitude of customer applications.
The 4150 is supplied with a robust, solid epoxy sensor which eliminates the risk of probe damage during use. This standard sensor has a nominal cell constant of 1.00. The meter also enables the digital selection of cell constant values between 0.015 and 19.99 to facilitate the use of the wide range of cell options offered. The assigned cell constant values can be checked and updated by the use of standard solutions.
In addition, the 4150 is configured to automatically recognise 3 common conductivity values across the measuring range (10µS, 1413µS and 12.88mS). Results can also be displayed in TDS (Total Dissolved Solids) using an in-built conversion factor of 0.66.
The reference temperature is selectable to be 18, 20 or 25°C, and the temperature coefficient can be digitally set to any value between 0 and 4.00%/°C (with a default value to 1.90%/°C, a value which is acceptable in many analytical situations)
High quality waterproof connectors (to IP67) allow rapid interchangeability of electrodes, whilst maintaining waterproof integrity. The connector incorporates a locking ring to guard against accidental disconnection or ingress of moisture.
