(1) A Micro-Chamber/Thermal Extractor M-CTE250(T)(i) (Markes International Inc., UK) was used with a TY9700 digital hygrothermograph (Tianyue Environmental Protection Technology Co., Ltd., Beijing, China).
A hygrothermograph was used to measure air temperature and relative humidity (SK-110TRH, SATO, Tokyo, Japan).
Both temperature and relative humidity were recorded on simple graph paper using a hygrothermograph (Mechel -15+45C, Italy) placed inside the glass house.
Temperature and humidity inside the device were measured by a hygrothermograph every 4 h when counting the number of psyllids and maintained at 25 [+ or -] 1[degrees]C, 60 [+ or -] 2% RH.
Based on the structural characteristics of the steel box girders and the steel arch towers, two sections of steel box girder and four sections of steel arch tower at the junction of steel box girder and steel arch tower have a hygrothermograph. A networked-edition DSR temperature and humidity recorder is used to monitor the temperature and humidity of the steel box girder and steel arch tower, a photograph of which is shown in Figure 5 and the main technical specifications are presented in Table 2.
And the relative humidity in the chamber was monitored by using a hygrothermograph. Humidity was turned in the range between 51% RH and 78% RH under fixed temperature of 21.9[degrees]C.
Humidity and temperature were measured with a hygrothermograph (Control Company--Friendswood, Texas, USA).

Trays were moved to a growth room where temperatures ranged from 15.5[degrees] to 22.4[degrees]C, light intensity was 145 umol/s/[m.sup.2] (which was maximum intensity available within room), and relative humidity ranged from 32 to 46% as measured with a hygrothermograph. A photoperiod of 16-hrs light/8-hrs dark was maintained in both the chamber and the growth room.
Among new products are double junction, waterproof pHTestrs; waterproof pH/con meters; microscopes; and a mini-drum hygrothermograph. OAKTON Instruments, Vernon Hills, IL 60061
The site was instrumented with two automatic weather stations backed up with a hygrothermograph housed in a standard instrument shelter and a weighing-recording rain gauge.
Temperature was recorded by using the clinical thermometer, minimum-maximum thermometer and hygrothermograph to minimize the errors.
