Description
The DT-2234C+ Handheld Digital Laser Photo Tachometer is a high-precision, non-contact diagnostic tool designed to safely and accurately measure the rotational speed (RPM) of high-speed machinery. By combining microcomputer LSI circuitry with a precise quartz crystal time base, it delivers rapid, drift-free measurements without touching hazardous moving parts.
Key Features
- Safe Non-Contact Senses: Utilizes a built-in Class II laser beam targeting system to track object rotations via a small piece of adhesive reflective tape.
- Automatic Internal Memory: Instantly logs data during tests, allowing users to automatically recall Maximum (MAX), Minimum (MIN), and the Last recorded value by pressing the MEM button.
- High Contrast LCD Display: Features a large, clear 5-digit, 18mm (0.7″) segmented screen that reduces readability issues in poorly lit maintenance bays.
- Comfortable Ergonomic Enclosure: The physical housing is contoured symmetrically to comfortably match either the left or right hand during extended field usage.
- Low Battery Notification: Automatically triggers an on-screen warning icon when internal battery voltage drops below optimal operational thresholds.

Solar panels are a clean and ecological source of electricity. Obtaining this energy, however, poses several challenges for device designers. The amount of energy produced by the panel is strongly dependent on the angle of incidence and the intensity of the light falling on the surface of the cells. This, in turn, leads to unstable power supply parameters at the output, as even shading a small part of the panel may drastically reduce the efficiency
The optimal solution to the above-mentioned problems is the use of a set consisting of a solar panel, a battery and a charge controller. Such a set allows to ensure constant parameters of power supply to receivers and also to store energy produced excessively for later use
The SCC-30A-PWM-LCD solar charge controller allows you to connect panels both in series and in parallel – remembering not to exceed the permissible values of current and voltage at the input of the device. Due to the operating characteristics of the PWM controllers, it should be remembered that when the panels are connected in series, the rated voltage at the output for charging the battery is 24V.
