PROPOSING WITH BRAND NAME LEATHER CASE (retail price 20 USD) !
You are bidding for MKS-05 "TERRA-P"- multifunctional radiometer-dosimeter. It is first pocket device for measurement of radiation for minor price. It really "people dosimeter". But notwithstanding small price, MKS-05 "TERRA-P" is fully functional radiation-metric device. It use in army, in special government organizations.
In modern world, especially in industrial countries, in big towns many radioactive substances use in production, in chemical plants, in nuclear power stations. Usually radioactive waste products is bury. But not rarely happen damage in depository, under transportation. Often unfair businessman's save on utilization. Radioactive substances appear in earth, in air, in water. Next it's come to food, building materials, drinking water.
There case which happened with me. I build house. I ordered 10 tons sand for building mortar. Dosimeter was with me in pocket. Previously I set it to 0.30 mSv/h. When track with sand arrived, my dosimeter started to squeak. When I took it from pocket, dosimeter has displayed 0.75 mSv/h. It more than twice more maximum norm.
The Terra-P dosimeter will make you sure that your building site is radiation safe and the building materials are not contaminated. Quite often radioactive materials contained in soil may also severely harm your and your children's health.
 Most of our time is spent at home. Everyday life trifles like kettle boiling, morning sun shining, coffee smelling, doorbell ringing etc. are common for our five senses. But what about gamma and beta radiation? It is not easily detected by our sense organs! There is a way out! Buy an extra "sense" that will keep working "without rest" for 6000 hours
Every person needs a good rest after intensive work. The Terra-P with small dimensions easily fits in the knapsack pocket and will without doubt alarm about the "hot" place to avoid.
The Terra-P dosimeter allows monitoring the contaminated food products you buy, to make you sure about the quality of vegetables and fruit that are being sold on the markets
It may happen sometimes that somebody would want to harm your health. State-of-the-art technologies make it possible for your enemies to embody their schemes by setting articles containing radioactive elements into your everyday life, which slowly but surely affects your health. The Terra-P for everyday use will instantly detect the like sources of danger and alert.
FEATURES
 |
The main control keys are the MODE and THRESHOLD buttons. |
| Press shortly the MODE button to switch the dosimeter on. |
 |
The Terra-P includes four operational modes: measurement of gamma radiation equivalent dose rate, measurement of gamma radiation equivalent dose !(TERRA-P is unique among pocket dosimeters. Only TERRA-P able to measure this parameter. It very important parameter which show how many of radiation energy absorbed body and how long time man can stay in zone with high radiation), clock, and alarm clock. Press the MODE button to switch the operational modes of the dosimeter. |
 |
By default, the dosimeter is switched in the mode of measurement of gamma radiation equivalent dose rate, which is indicated by the "µSv/h" symbol. |
| Use the THRESHOLD button to run the programmed threshold level and change its value. At excessive threshold level the dosimeter will alarm about hazard (by default, the preset threshold value is 0.30 µSv/h, an average permissible radiation level for premises). Zero the previous measurement results by the THRESHOLD button. |
 |
To enter the mode of measurement of gamma radiation equivalent dose, press shortly the MODE button. Four digits and "mSv" symbol appear on the display. |
| Note. In case of natural (c 0.1 µSv/h) gamma radiation background, an ED change by one low-order digit occurs on the display in 10 hours, and the "0.001 mSv" result, equal to 1.0 µSv, is shown on the digital indicator. |
 |
The clock mode of the dosimeter operation follows and two periods start blinking with one-second interval. |
 |
The alarm clock mode of the dosimeter follows and two steady periods appear on the display. Program the alarm clock with the help of the MODE and THRESHOLD buttons. The alarm clock signal symbol is indicated on the display at that. |
| Note. The alarm clock operates even if the dosimeter is off.
Manual on English you can download here. Also, I send English manual to each customer. |
Package set consist: dosimeter-radiometer MKS-05 "TERRA-P", operating manual, a leather case, which allows carrying the device on a waist-belt or a wristlet and cardboard box.
