Metalworking Fluid Monitoring

What Evil Lurks in your Sump?

Stop guessing....

Watch concentration, pH, and temperature in real time. Sensors connect to the secure watchLINK Hub, which delivers measurements to the MISCO Cloud over an encrypted cellular IoT network. No plant IT required.

The Cost of Guessing

The hidden cost of running blind

When concentration and pH drift unseen, the loss shows up everywhere except your monitoring screen: in coolant you replace too often, in machines that stop without warning, and in tools that wear out early. Continuous measurement turns those hidden costs back into recoverable savings.

watchLINK system architecture: sensors to hub to MISCO Cloud
System Architecture

From sensor to cloud, in one clean monitoring loop


TRACK  •  TREND  •  ANALYZE  •  PREDICT

Each installation begins with a secure watchLINK hub. From there, you select the sensors and accessories your application needs. The Hub acts as the secure sensor gateway, collecting measurements from connected concentration, temperature, and pH sensors and transmits them to the MISCO Cloud over an encrypted cellular network. Because each hub has its own cellular modem, it eliminates a single point of failure common with most gateway networks.

Secure cellular communication

Encrypted uplink independent of plant networks.

No plant IT required

Installs without network integration or firewall changes.

Cloud-based measurement history

Concentration, pH, and temperature logged over time.

Modular sensor selection

Add concentration, pH, and accessories per sump.

watchLINK Hub

Industrial IoT integration without the usual IT drama

The secure gateway for your monitoring system

The watchLINK Hub connects your sensors to the MISCO Cloud. It collects measurements from concentration, temperature, and pH sensors and sends them securely over an encrypted cellular connection. Because it communicates independently of plant networks, installation is simplified and IT involvement is minimized. At no time is your local network exposed to risk

PHwatch pH Sensor

Inline pH Monitoring for Fluid Control

The PHwatch sensor features a planar hybrid industrial pH sensor that elinates fragile glass electrodes. Measuring the pH of metalworking fluids helps maintain emulsion stability, corrosion protection, microbial control, odor prevention, and tool performance, while serving as an early warning signal for problems. It connects to the watchLINK Hub and delivers pH measurements to the MISCO Cloud. Paired with inline concentration monitoring, it helps provide a more complete view of metalworking fluid condition, supporting control over corrosion, bacterial growth, and fluid instability.
