SM4P, SediMeter for Pro2022-03-09
We have listened to our customers and designed a new model of the SediMeter that we call Pro because it is targeted to professional users, who typically need to install the instrument on a platform or structure. This excludes the use of the screw-down anchor and holder. The SM4P therefore has a sensor with the same outer diameter as the holder tube of SM4, i.e. 20 mm. As a side effect, this means the instrument is much stronger also. On the down side, the sensor is not protected by any holder tube from scratches, but to compensate for that, we have designed it so that it is relatively easy to rebuild the instrument with a new outer shell. Another benefit of this construction is that it ends up less expensive than the SM4 model, which will be an advantage to monitoring projects that typically need many units deployed. All features are the same as for the original SM4 model. To compensate for lack of space for an AA battery, we are using two AAA batteries to get acceptable battery lifetime. Otherwise they are identical.
