This meter is quite simple and easy to use. ph and temperature of liquid solutions automatically. This costs a little more than some other portable pH meters, but so far I really like this meter. The sponge was completely dry when it arrived, but I quickly dampened it with a storage solution sold separately and it still seems to be working fine. This meter has allowed me to diagnose why my tomato plants continue to have weird spots after years of success. If this meter lasts more than 18 months and uses it to water twice a week I will be a happy camper. .and will definitely upgrade this meter to five stars.
