Carbon Monoxide

Poor indoor air quality is often overlooked when compared with outdoor airbourne issues. Although most people won't experience any symptoms from prolonged exposure to carbon monoxide levels between 1 and 70 ppm - although some heart patients may get increased chest pain - as CO levels increase above 70 ppm symptoms become more noticeable and can include headache, fatigue and nausea. The carbon monoxide output from boilers and chemicals used indoors can be monitored using Lascar's USB data loggers, ensuring safety in the very environments we spend a majority of our time. 


Another issue facing many homes and offices is excess humidity or condensation damp which left unchecked and untreated can lead to problems such as black mould. Whilst mould is in itself unsightly, it can also lead to a wealth of health issues including headaches, fatigue, sinus problems, sneezing, skin rashes and even depression. Lascar has a wide range of both standalone USB and WiFi data loggers to monitor humidity levels, which left too high could cause mould issues, and too low could also have an effect on both the health of staff and building structures themselves.

Specially designed for indoor environmental monitoring, our next-generation EL-SIE range measures ambient temperature, humidity and pressure and can store over 1 million readings. Advanced onboard software means there is nothing to install on your PC or Mac – simply connect the logger with a USB cable and use your web browser to configure the device and view, analyse and download your data. 

Remote Monitoring

Remotely monitor your environments, improve your energy efficiency and air quality and get early warning of poor conditions with instant alarm notifications using our WiFi connected devices. Lascar's WiFi sensors are easy to set-up using a smartphone App. Simply log on to your EasyLog Cloud account from any internet enabled device to access secure real-time and historical data, remotely change individual sensor settings and create individual locations for one or multiple devices.

Pre-Calibrated Probes

Need to re-calibrate your sensors annually? Leave your EL-MOTE-TH sensor in the field and simply purchase a new pre-calibrated probe. No loaner stock. No disruption. Simply replace the probe and keep logging.

Energy Efficiency 

The ongoing management and control of energy expense is greatly assisted by audits designed to show energy use across homes and businesses. Identifying peaks and troughs of consumption or the significance a single appliance can make to the bottom line, suggests how we can change energy habits to reduce cost. Use Lascar's energy data logging solutions to measure multiple parameters of energy, provide alarms where necessary on out of range use and convert those readings into multiple currencies. 

Lascar Products in the Field

Don't take our word for it. Read how some of our customers have been using Lascar data loggers in the field to track temperature and humidity in the workplace and at home. From the Property Care Association using our USB data loggers for damp control to Audio Mix House using our WiFi loggers to monitor the temperature and humidity in their recording studio to prevent damage to their expensive equipment to the Texas Spirit Seekers using our USB loggers to monitor temperature and humidity fluctuations in the hunt for paranormal activity to Airway Air Conditioning who used WiFi loggers to monitor the temperature and humidity in school classrooms that couldn't be disturbed.

What Do The Experts Say?

"The level of CO concentration is measured using a system called Parts Per Million (PPM). For example, 100 PPM CO means that for every 999,900 molecules of air, there are 100 molecules of CO. 9 PPM is the maximum recommended indoor CO Level. Further information can be read here."
