Mini Thermo-Anemometer

This carbon dioxide detector measures CO2, air temperature and humidity. A useful tool to help to regulate ventilation in enclosed spaces such as classrooms, indicating when fresh air should be allowed in to help remove air that contains virus particles and to help prevent the spread of Covid-19. People exhale carbon dioxide when they breath out. If there is a build-up of this in an area it can indicate that ventilation needs improving. This device adopts a high-precision non-dispersive infrared CO2 sensor that detects CO2 accurately and sensitively. Containing a high-capacity rechargeable lithium battery, making it easily portable. To preserve electricity, it powers off after 30 minutes of inactivity. A USB charging cable is also provided allowing simple recharging using either a PC or mains plug. Product specifications: CO2 concentration measurement; •Range: 0 to 9999ppm •Accuracy: +/-75ppm / +/-5% of rdg •Resolution: 1ppm Temperature and humidity detection; •Temperature range: -20 to +70°C •Temperature accuracy: +/-2°C •Temperature resolution: 0.1°C •Humidity range: 0 to 100%RH •Humidity accuracy: +/- 3.5%RH (20 to 80%RH) otherwise +/-5%RH •Humidity resolution: 0.1%RH Battery: 1000mAh rechargeable lithium battery Battery charge: USB 5V charging Dimensions: 90mm x 60mm x 47mm LCD dimensions: 49mm x 38mm Operating conditions: 0 to +50°C

Observe living creatures in this ventilated viewing pot with 5x magnification lid. Clear base with micro ruler.

These Pooters are designed not to be perfectly round so that bugs will find a crevice to hide in and are easier to observe. The jar contains two holes; one of which has a fine mesh covering to prevent bugs being drawn into the mouth. Two lengths of tubing (removable for easy washing) are supplied.

Use in conjunction with an accurate millisecond timer to calculate acceleration due to gravity. The timer starts when the ball bearing is released from the release unit, the base has an integral vibration sensor which stops the clock as the ball bearing hits the impact plate. Replace the ball bearing, reset the timer and the unit is ready to go again. When used with Lascells timers or other models with de-bounced inputs no additional power is required. If the timer used is found to have “bouncy” inputs then a 4 second delay can be added to the impact plate outputs by powering the unit with 9 V DC. Supplied with: Full instructions Base, release unit, 12 mm ball bearing, 8 mm ball bearing Features: Easy setup with integral vibration sensor No power required for millisecond timers with de-bounced inputs Two ball bearings allowing comparison of different masses Over-moulded rubber landing plate. Integrated de-bounce circuitry to add 4 second delay to outputs. (9 V DC required)

The Lascells Millisecond Timer is a fully functional, easy to use millisecond timer and has a clear, 4 digit LED display. Three sockets provide START and STOP inputs which respond to any change of switch settings i.e. normally closed to open or vice versa making triggering very simple and reliable. A single switch changes the timer from GATE 1 start and stop to GATE 1 start GATE 2 stop. In addition 3.5 mm sockets are provided to allow Lascells timer light gates to be connected. The timer has millisecond resolution for times up to 10 seconds and then the display auto-ranges for longer periods up to 9999s with corresponding reduced resolution. Supplied with mains plug-top adaptor and full instructions.
