Product Details: Conductivity meter with USB logger type M4036
The M4036 conductivity meter is suitable for water, waste water or pure water conditioning in continuous or batch-type operating modes, to control concentration in cooling towers, monitoring of PEM electrolysers for hydrogen production or for general chemical process monitoring.
The very compact conductivity meter type M4036 was developed with a 3.5 inch IPS display. Increased brightness allows reading of the measured value even in direct sunlight. The capacitive touch screen allows intuitive and fluid operation.
The two-point controller consists of two potential-free limit contacts which can be electronically adjusted over the entire range. The limit value contacts can be used to control alarm devices, dosing valves and dosing pumps, among other things. The current measured value, the temperature, as well as the device status are continuously displayed.
The instrument is supplied with a galvanically isolated wide range power supply from 20 to 253VAC/DC and needs as a pure measuring instrument a conductivity probe to be ready for operation. Commercially available probes with K-factors 0.01, 0.1, 1.0 and 10.0 cover a dynamic range from 1µS to 200mS (example: M8836S). The cable length of the probe is automatically compensated internally and does not influence the measurement signal.
Temperature compensation is performed either manually or by an external Pt-100 temperature sensor. A defective Pt-100 sensor or a broken wire is immediately indicated and triggers an alarm. The conditions for triggering an alarm can be defined.
All instrument settings can be protected by means of access codes. A USB stick can be used to automatically record the measured values. The device also has two freely programmable, galvanically isolated signal outputs.
