MIK-TDS6012 Conductivity sensor

The MIK-TDS6012 is a stainless steel conductivity sensor that combines EC and TDS measurement in one cost-effective design. It can also be used as a resistivity sensor, and supports boiler water, RO water treatment, sewage treatment, pharmaceutical and other liquid monitoring applications.

Together with a conductivity meter, it measures EC (electrical conductivity), TDS (total dissolved solids) and resistivity.

• K = 0.01: 0–20 μS/cm
• K = 0.1: 0–200 μS/cm
• K = 1.0: 0–2000 μS/cm
• K = 10.0: 0–20,000 μS/cm
• K = 30.0: 30–60,000 μS/cm

Choose the cell constant according to your expected conductivity. K = 0.01 or 0.1 is used for pure water, RO permeate and boiler feed water; K = 1.0 for tap water and general process water; and K = 10.0 or 30.0 for high-conductivity solutions such as some wastewater and brines. Send us your expected range for a recommendation.

• Conductivity accuracy: ±1% FS
• Temperature accuracy: ±3 °C

NTC10K or PT1000 are available as options. Choose the element that matches your conductivity meter.

The standard temperature range is 0–60 °C, and a high-temperature version up to 120 °C is available. Please tell us your process temperature when ordering.

The pressure rating is 4 bar.

NPT 1/2" and NPT 3/4" threads are available.

The sensor is made of stainless steel and has IP68 ingress protection.

Yes. The MIK-TDS6012 is designed to support boiler water and RO water treatment monitoring. Low cell constants (0.01 or 0.1) are typically used for these low-conductivity applications.

Asmik options include the MIK-TDS210-B, MIK-TDS210-C and MIK-EC8.0. Please make sure the meter supports the selected cell constant and temperature element.

• Install the sensor so the electrodes are fully immersed and free of air bubbles.
• For low-conductivity water, use a flow-through or in-line installation to avoid contact with air.
• Keep the electrodes away from pipe walls and other metal parts where possible.
• Ensure the flow is steady and representative of the process.

Please follow the installation manual or contact our engineers for site-specific requirements.

Calibration is generally performed by entering the cell constant in the meter or by using a conductivity standard solution close to your process range. Keep the electrode surfaces clean, as deposits, oils and biofilm affect the reading, and check the calibration after cleaning.
