Electronic sludge level meter – portable, battery powered device designed to measure the depth of the sludge. It is used to monitor changes in sludge level in sedimentation tanks, separators, during drilling, tank maintenance, etc. Information from the probe is transmitted to a control panel located on the drum and generates an optical-acoustic signal in the event of contact with the sludge. It has the ability to change the polarity of operation (submersion generates an alarm, or ascent generates an alarm).


The deepSLUDO is a portable battery-powered device. The body is made entirely of metal. Inside the drum there is an electronic system that controls the operation of the device. There is a control panel at the front. A cord in the form of a tape with a metric scale is wound on the drum. At the end of the tape there is a measuring probe made of stainless steel and polyacetal.
Battery powered R9 9V with a built-in drawer for easy battery replacement. The battery used allows you to work for many years. It is recommended to use batteries for industrial applications – with the description INDUSTRIAL. This type of battery ensures a longer service life.
The deepSludo has an innovative solution that allows you to change the direction of the UP-DOWN reaction. At the moment of starting the device, immersion of the probe in water generates an acoustic and optical alarm. On the other hand, switching the operating mode enables operation in the reverse logic, and then when the probe emerges from the water, it generates an acoustic-optical alarm.
The device is equipped with an intelligent electronic system that controls the battery life and the status of turning on or off the deepTESTER. AUTO-OFF function – supervises the work of a deepTESTER and in a situation when you forget to turn off the device, the system will automatically turn off its power and will not discharge the battery.
BRAKE – on the left side the deepTESTER has an adjustable brake that stops the drum from being unrolled during the measurement work as well as for transport to the place of use. The deepTESTER has a solid metal construction. The stand is made of welded tubes and powder coated, which protects the structure against corrosion for many years of operation. The drum is also made of thick pressed sheet and protected with a zinc coating. The deepTESTER construction ensures long-term use in harsh environmental conditions.
The ergonomic handle of the deepSLUDO was designed so that carrying the drum and working while unrolling and rolling the tape was a pleasure. The diameter and specially profiled shape under the fingers makes the deepTESTER stick firmly in the hand.
The acoustic signaling is carried out using the built-in buzzer. The immersion or ascent alarm is generated by a continuous signal of approximately 100 dB. The device also has a built-in battery level monitoring system and generates a repetitive, intermittent pulse signal when it detects a low battery voltage level.
Measuring tape with a sunken metal guide that protects against stretching the wire. Two-wire cable (2 copper and steel cross-overs), insulated over the whole length with abrasion resistant material. On the embedded steel tape, a graduation with an accuracy of 1 mm is printed under the coating. Available wire lengths are 15m, 30m, 50m, 100m, 150m, 200, 300, 500 or more.
The fixing of the cable in the probe housing has been secured with an elastic material preventing the tape from being broken or being rubbed when leaving the guide channel.
The measuring probe with a diameter of only 40mm and IP68 tightness allows the use of a sediment tester in holes with a very small diameter. The probe is made of stainless steel, enabling many years of work without damage. The measuring electrode has been placed inside the probe housing so that it is not exposed to damage when lowering in the guide channel.

The deepSLUDO has three built-in button functions described on the control panel. Pressing for 1 second activates the deepSLUDO, signaling it with a short sound and lighting the LED diode. A long press of the button switches the device off, which is signaled by a long beep and flashing of the LED diode. Pulse pressing during operation of the whirlwind enables to switch the UP-DOWN mode of operation (an alarm when it comes into contact with water or an alarm when it emerges from water).

SAFETY CASE – Bag securing the deepSLUDO against damage during transport and rest. It is made of three layers of thick material, interleaved with a sponge protecting against impacts. Dimensions are 45x35x25 cm.

SLUDO probe  operation – This video shows the principle of sludge recognition in the deepSludo device (only the probe and controller are shown in the video – not a deepSludo device). After the probe is immersed below the sediment level, the electronic system located in the probe housing transmits the information to the controller. The acoustics and optics are activated.
