Kontakt PCB PLUS spray 100ml

Sodium Persulfate B327 (PCB) Printed Circuit Board Etching 1kg features:
A compound for etching of printed circuit boards and pickling of copper. An ideal alternative to ferric chloride. It is readily soluble and does not crystallize from the solution. It etches evenly, ensures the sharpness of contours and minimizes undercutting. Usage: Dissolve the preparation in 0.5 l of water at a temperature of 50°C. Perform etching at 40°C (max. 50°C). Bath movement ensures quicker etching. The etching solution must not be stored in hermetically sealed containers due to the risk of developing overpressure and cracks.

High grade in the absorption of tin for professionals.

- The DHT22 humidity sensor is presented in a plastic body ideal for mounting on a panel or similar. It uses a capacitive sensor that returns a digital signal with the measurement - This sensor, unlike DHT11, is capable of measuring negative temperature values ​​and measures tenths of a degree
Characteristic:
- Operating voltage: 3 to 5.5 VDC - Humidity measurement range: 0-100% ± 2% accuracy
- Temperature measurement range: -40ºC to 80ºC ± 0.5º accuracy
- Maximum sampling rate: 2 seconds

Industrial Abrasive Scourer Pad 150x50mm Laminated Copper Plate PCB features:
Industrial abrasive scourer for laminated copper plate Cleaner for cleaning the laminated copper plate. Perfectly removes impurities such as oxides, sulfides and other similar establishments, as well as polished surfaces so that the copper substrate is better prepared.
It is also ideal for removing the remains of enamels, lacquers and other materials used during the creation of PCB tracks.

High sensitivity to Ammonia (NH3), Nitrogen oxides (NOx), Alcohol, Sulphides, Benzene (C6H6), CO2, smoke and other harmful gases.  The MQ-135 sensor is to sensible for other gasses in the air so that is not possible to get good values for CO2 from it.
MQ-135 Air Quality Sensor features:
- Main chip: MQ-135 natural gas sensor and comparator LM393
- Working voltage: 5V
- Current: 150mA
- Digital output: TTL 0/1
- Analog output: analog voltage sensing value
- Quick response features:
- Detection concentration:
   10ppm - 300ppm NH3
   10ppm - 1000ppm Benzene
   10ppm - 300ppm Alcohol
- Adjustable sensitivity with the potentiometer
